The “rise” of the muffin is caused by the release of ___________ gas trapped in the mix as it is heated. carbon dioxide hydrogen oxygen helium
Answer:
Carbon dioxide
Explanation:
In the making of the muffins, there are many ingredients are used including flour, egg, butter, sugar, and flavoring of fruits. There is also a raising agent, the baking powder or baking soda used that reacts with the batter.
This reaction form bubbles of carbon dioxide, trapped in the air spaces during the baking and muffin raises. Carbon dioxide makes muffins light, by lifting the batter as it bakes.

Note: The correct question is given below:
Which best describes why NH4+ can form an ionic bond with Cl-?
Its outermost shell gains one or more electrons from Cl-.
Its positive charge is attracted to the negative charge of Cl-.
It has a negative charge that is spread over the entire ion.
It has a nitrogen atom that is strongly attracted to Cl-.
Its positive charge is attracted to the negative charge of Cl-.
Explanation:
An ammonium ion is a positively charged ion which is composed of a molecule of ammonia and a hydrogen ion which are in a coordinate covalent bond due to the lone pair of electrons of the nitrogen atom in the molecule ammonia. The chloride ion however, has an extra electron which gives it a negative charge.
An ionic bond is formed between two oppositely charged ions by a transfer of electrons from one atom to another. It usually occurs between non-metals and metals. However, that formed between ammonium ion and chloride ion is between non-metals entirely.
Due to electrostatic attraction between the oppositely charged ions, an ionic bond is formed between ammonium ion, NH4+, and chloride ion, Cl-.

Choose the balanced chemical equation below that best represents the following reaction:
When baking soda (NaHCO3) reacts with hydrochloric acid (HCl), carbon dioxide bubbles (CO2) are created, along with water (H2O) and sodium chloride (NaCl).
NaCl + H2O → NaHCO3 +CO2 + HCl
CO2 +H2O + NaCl → NaHCO3 + HCl
NaHCO3 + HCl → CO2 + H2O + NaCl
HCl + NaCl + H2O → NaHCO3 +CO2
The balanced chemical equation :
NaHCO₃ + HCl → CO₂ + H₂O + NaCl
Further explanationA balanced chemical reaction shows that the number of atoms of the reactant and the number of atoms of the product is the same
When baking soda (NaHCO3) reacts with hydrochloric acid (HCl), carbon dioxide bubbles (CO2) are created, along with water (H2O) and sodium chloride (NaCl) .
This statement shows that
Reactants (located to the left of the reaction)
Baking soda (NaHCO₃) and Hydrochloric acid (HCl)
product (located to the right of the reaction)
Carbon dioxide(CO₂),water (H₂O) and Sodium chloride (NaCl).
So the reaction :
NaHCO₃ + HCl → CO₂ + H₂O + NaCl

How are convalent molecules named?
Covalent compounds are named by using numerical prefixes to identify the number of atoms in the molecule. E.g. Mono, Di, tri, tetra, etc.
In the naming, never use mono- for the first element.
The first element keeps its name.
The second element always end in the suffix -ide.
Drop the double vowel for the prefix and the element of the second element in the compound.
Hope this helped!

carbon and tin are both in the fourth column of the table which would you expect to have the greater electronegativity
Answer: Carbon
Explanation:
electronegativity decreases when you go down a column
The study of chemical bonds is called chemistry.
The correct answer is carbon.
The more negative charge present on an atom shows the electronegativity.
The attraction of the nucleus to the proton is also referred to as electronegativity.
The smaller the radius more the electronegativity.
Hence, the correct answer is Carbon as it has fewer atoms and a smaller radius.

For a certain chemical reaction, the bond energy of the reactants is 43 kJ, and 35 kJ of energy is released. For energy to be conserved, what is the bond energy of the products?
Answer:
78kJ
Explanation:
Energy change = Energy in (reactants) - Energy out (products)
According to this question, energy is released, meaning that the reaction is EXOTHERMIC. Hence, the energy change will be negative (-) i.e bond energy of reactants is greater than bond energy of products.
Energy in = bond energy of reactants = 43kJ
Energy out = bond energy of products = ?
Energy change of exothermic reaction = -35kJ
Therefore;
-35kJ = 43kJ - x
x = 35kJ + 43kJ
x = 78kJ
The bond energy of the products is 78kJ.
Astronomers observed that the orbit of Uranus was not uniform. Therefore, they hypothesized the existence of another planet. This is an example of scientific investigation being led by _____.
Inductive Reasoning
Deductive Reasoning
Answer:
This is an example of scientific investigation being led by inductive reasoning.
Explanation:
Inductive reasoning is the type of reasoning used to make broad generalizations from specific observations. We have certain pieces of data and make conclusions based on them. In the given example, astronomers have made a specific observation - that the orbit of Uranus isn't uniform. Based on that fact, they made a broader conclusion - that there is another planet. There are probably more things that could lead to the same conclusion.
The opposite is deductive reasoning, where a person starts off with a broad generalization and tries to make specific, logical conclusions based on it.

A particle has a nucleus that contains 10 protons and around the outside it has 8 electrons. What is the overall charge of the particle?
0
+2
-2
+18
Answer:
The charge is +2
Explanation:
Protons are positive, electrons are negative. 10-8=2.
+2 :)
A particle has a nucleus that contains 10 protons and around the outside it has 8 electrons, the overall charge of the particle is +2. Therefore, the correct option is option B.
What is atom?The smallest unit of matter that may be split without producing electrically charged particles is the atom. It is also the smallest piece of substance with chemical element-like characteristics. As a result, the atom serves as the fundamental unit of chemistry.
Space makes up the majority of an atom. The remainder is made up of a cloud of electrons with negative charges around a positive-charged nucleus made up of protons and neutrons. Compared to electrons, that are the lightest positive ions in nature, the nucleus is tiny and dense. A particle has a nucleus that contains 10 protons and around the outside it has 8 electrons, the overall charge of the particle is +2.
Therefore, the correct option is option B.
