Answer:
D10 is answer
Explanation:
Magnetism can result from unpaired electrons in a given ion of an element, depending on the spin states of the electrons and d10 is fully filled
The d 10 is the d shell configurations which is most likely to be the best magnet.
What are configurations?Configurations are defined as the way that parts are joined together to form the computer system. The arrangement of electrons scattered throughout the orbital shells and subshells is depicted by the electron configuration of an atom. Divide the periodic table into pieces to represent the atomic orbitals, the areas where electrons are stored, in order to determine an electron configuration. The s-block is represented by groups one and two, the d-block by groups three through twelve, the p-block by groups thirteen to eighteen, and the f-block by the bottom two rows.
Depending on the spin states of the electrons and whether or not d10 is completely filled, magnetism can emerge from unpaired electrons in a specific ion of an element.
Thus, the d 10 is the d shell configurations which is most likely to be the best magnet.

Use the information given to calculate the average atomic mass of element Z. Z- 56 is 70% abundant and Z-59 is 30% abundant.
Answer:
56.9 amu
Explanation:
Depending on the number of isotopes an element has, the Average atomic mass of isotopes of an element can be calculated using:
(atomic mass of isotope1 × decimal abundance of isotope1) + (atomic mass of isotope2 × decimal abundance of isotope2)
According to this question, two isotopes of element Z were given
- Isotope Z- 56 with atomic mass 56 is 70% abundance. This means that its decimal abundance is 0.70
- Isotope Z- 59 with atomic mass 59 is 30% abundance. This means that its decimal abundance is 0.30
Therefore, average atomic mass of element Z is:
= (56 × 0.70) + (59 × 0.30)
= (39.2) + (17.7)
= 56.9

Which of these would have particles with the highest kinetic energy?
ice
water
water vapor
Answer:
water vapor
Explanation:
because gas molecules moves the fastest
Answer:
water vapor
Explanation:
Liquid water molecules have less freedom to move around. While molecules of water vapour have more freedom to move around as there is larger space between the molecules. Hence, the kinetic energy of water molecules is more as compared to the kinetic energy of liquid water

What would pressure be if volume was 0
Answer:
The lower the temperature, the lower the pressure inside of the sphere. If the exact values were plotted out, a linear relationship would be apparent. Extrapolating this line to the point where there would be no pressure yields absolute zero, which is about -273.15 degrees Celsius.

Example of Anchoring Bias
Answer:
Here is an example of anchoring Bias
If I were to ask you where you think Apple’s stock will be in three months, how would you approach it? Many people would first say, “Okay, where’s the stock today?” Then, based on where the stock is today, they will make an assumption about where it’s going to be in three months. That’s a form of anchoring bias. We’re starting with a price today, and we’re building our sense of value based on that anchor.
Anchoring bias occurs when people rely too much on pre-existing information or the first information they find when making decisions. For example, if you first see a T-shirt that costs $1,200 – then see a second one that costs $100 – you're prone to see the second shirt as cheap.
Anchoring or focalism is a term used in psychology to describe the common human tendency to rely too heavily, or "anchor," on one trait or piece of information when making decisions.

A brick delivery truck parks on a roadside scale that measures 4 m by 6 m. If the brick truck weighs 60 000 N, what pressure does the scale put on the spring below?
Explanation:
Area = Length × Breadth
A = 4 × 6
A = 24m square/ 24m sq.
Force = Pressure × Area
Force = 60,000 N/ 60,000 Newton
Pressure = Force/ Area
P = 60,000/24
P = 2500 Pa
SCIENCE A meteorologist uses a weather map to explain an upcoming change in weather. The map shows a blue line with triangles approaching a red line with semicircles. Based on the map, which weather prediction is most valid? (1 point) A a significant drop in temperature will occur across the area. B There is no chance of precipitation in the forecast. C Warm temperatures will replace cold temperatures. D Humidity levels will rise.
Answer:
The correct option is D) Humidity levels will rise
Explanation:
A rise in humidity means that it is most likely there is going to be a rain.
When blue semi-circle lines with triangles approach red semi-circle lines it is a situation where cold front is approaching a warm front.
The resultant effect is that the warm and cold air both come to a standstill. This will most likely trigger cloud and fog and may even lead to rain.

B) 2.64
C) 37.89
D) 75.78
E) 1.27
Please give an answer and an explanation, thanks!
Answer
C
Explanation:
i remember learning this
Mass percentage does not have any unit as numerator and denominator contains the same unit. The percentage of sulfuric acid in solid sample is 38.07%.
What is percentage by mass?Mass percentage represents the the percentage of each element that is making a particular compound.
Mathematically,
Percentage of mass = (component’s mass ÷ total mass) x 100%
[tex]\rm 2 NaOH aq + H _{2} SO _{4} aq → Na _{2}SO _{4}aq + 2 H _{2} O[/tex]
Volume of NaOH solution = 32.22 mL = 0.03222 L
Concentration or molarity of the NaOH solution = 0.2012 M
Moles of NaOH : 0.03222×0.2012=0.006444mol
2 moles of sodium hydroxide reacts with 1 mole of sulfuric acid.
0.006444mol of sodium hydroxide reacts with =0.006444÷2=0.003222mol of sulfuric acid.
Mass of sulfuric acid neutralized = 0.003222 moles × 98.08 g/mol =0.31601376g
Percentage of sulfuric acid in solid sample= (0.31601376g÷0.8390g)×100=38.07%
Thus the percentage of sulfuric acid in solid sample is 38.07%.

A.
mortality
B.
maternity
C.
infirmity
D.

Answer: A
Explanation: Mortality means death. And it is a primary goal of Development Goals
Reducing child mortality, or rate of death, is one of the primary goals of the UN’s Millennium Development Goals and the correct option is option A.
What is Mortality?Mortality is defined as the state of the individual being dead. The mortality rate is the death rate of a population which is calculated on the basis of the deaths in the particular region.
Mortality as one of the components of demography is measured as mortality rate.
Mortality meaning provides the basis for mortality rate and its estimation. Mortality is the possibility of and susceptibility to death, and hence, the rate of mortality or the death rate is the measurement of the number of deaths that occur in a particular population, scaled to the size of that population per unit of time.
Therefore, Reducing child mortality, or rate of death, is one of the primary goals of the UN’s Millennium Development Goals and the correct option is option A.
