what is the value of log1.004?​

Answer:

[tex]\boxed {\boxed {\sf C. \ More \ protons \ are \ present \ in \ the \ atomic \ nucleus}}[/tex]

Explanation:

First, let's define atomic number.

    ⇒ The number of protons in an atom.

    ⇒ This number determines the identity and properties of the atom

So, atomic number relates to protons. There is an increase in atomic number, so there must be more protons in the atom. We can eliminate choices A and B, because they pertain to electrons.

We are left with choices C and D. The difference between them is the location of the protons.

Protons are part of the nucleus of the atom: the dense, central region of the atom comprised of nucleons: protons and neutrons.

Electrons, not protons, orbit the nucleus, so  D is not correct.

We are left with choice C: more protons are present in the atomic nucleus

Answer: They are all odorless, colorless, monatomic gases with very low chemical reactivity.

Answer:

The solution is

Explanation:

a = f/m

a =7/14

a=1/2

a=0.5

Acceleration of bike is 0.5 m/s²

Force used in push = 7 N

Mass of bike = 14 kg

Acceleration of bike

Force = Mass × Acceleration

Force used in push = Mass of bike × Acceleration of bike

7 = 14 × Acceleration of bike

Acceleration of bike = 7 / 14

Acceleration of bike = 0.5 m/s²

500 mL of He at 98 kPa expands to 750 mL. Find P2.

P₂ = 65.3 kPa

Given

V₁=500 ml

P₁=98 kPa

P₂

Solution

Boyle's Law  

At a constant temperature, the gas volume is inversely proportional to the pressure applied  

[tex]\rm p_1V_1=p_2.V_2\\\\\dfrac{p_1}{p_2}=\dfrac{V_2}{V_1}[/tex]

Answer:

6.8 liters of propane gas will undergo a complete combustion with 34.0 L of oxygen gas.

Explanation:

Given;

combustion reaction of propane and oxygen;

C₃H₈ + O₂(g)  → CO₂(g)     + H₂O(g)

Balance the chemical reaction as follows;

C₃H₈ + 5O₂(g)  → 3CO₂(g)   +   4H₂O(g)

From the balanced equation;

1 mole of C₃H₈ ---------------- 5 moles of 5O₂(g)

x Liters of C₃H₈ ----------------- 34.0 Liters of O₂(g)

x = 34 liters / 5

x = 6.8 liters

Therefore, 6.8 liters of propane gas will undergo a complete combustion with 34.0 L of oxygen gas.

Answer:

Characteristics of Sedimentary Rocks. ● The color of the sedimentary rock is determined by the content of the strata that were pressed together to form it. If the layers have a high organic content, the rock is usually gray to black in color. On the other hand, high amount of minerals give the rock the color of the mineral.

[tex]\boxed {\boxed {\sf A. \ About \ 5.14 *10^{24} \ molecules \ H_2O}}[/tex]

Explanation:

To convert from moles to units, we must use Avogadro's Number: 6.022 * 10²³

This tells us the number of units (molecules of water in this problem) in 1 mole of a substance (water). We can use it as a ratio or fraction.

[tex]\frac{6.022 *10^{23} \ molecules \ H_2O}{1 \ mol \ H_2 O}[/tex]

Now, we can multiply this fraction by the moles of water (8.54) given.

[tex]8.54 \ mol \ H_2O*\frac{6.022 *10^{23}\ molecules \ H_2O}{1 \ mol \ H_2 O}[/tex]

When we multiply, the moles of water will cancel out.

[tex]8.54 *\frac{6.022 \ molecules \ H_2O}{1 \ }[/tex]

Since the fraction has a 1 as a denominator, we can remove it. The problem will be a simple multiplication problem.

[tex]8.54*6.022 \ molecules \ H_2O[/tex]

[tex]5.142788*10^{24} \ molecules \ H_2O[/tex]

The original measurement of 8.54 has 3 significant figures (8, 5, and 4). Therefore, we must round our answer to 3 sig figs, which is the hundredth place in this case.

The 2 in the thousandth place tells us to leave the 4 in the hundredth place.

[tex]5.14 *10^{24} \ molecules \ H_2 O[/tex]

There are about 5.14*10²⁴ molecules of water in 8.54 moles.

Answer:

5.14 x 10^24 molecules of H2O.

Answer:

option 1. Two substances in a mixture differ in density and particle size. These properties can be used to separate the substances. These properties can be manipulated in order to have a better separation between the two substances.

Explanation:

Answer:

Two substances in a mixture differ in density and particle size. These properties can be used to separate both of them using the separating funnel or using filtration (filter paper).

Explanation:

Since their densities are different, one substance should float above the other in the mixture which allows for the separating funnel to let the substance sinking below (with the heavier density) to flow out first before changing the beaker to let the lighter substance flow out.

The substance with a bigger particle size would not be able to pass through the filter paper unlike the substance with the smaller particle size as the filter paper's pores is not big enough for it to pass through, separating both substances (with one on the paper and the other outside the filter paper, preferably in the beaker placed below the paper).
