Answer:

Ans => C => 43.3%

Explanation:

2CO + O₂ => 2CO₂

Given 1g CO = 1g/28g·mol⁻¹ = 0.036 mol CO

b/c coefficient of CO = coefficient of CO₂ => moles CO₂ = 0.036 mol = 0.036mol x 44g/mol = 1.57 gCO₂ (theoretical yield)

%Yield = (actual yield/theoretical yield) x 100% = (0.68g/1.57g) x 100% = 43.3%

Lydia and Damien should select the bottle of weak base with high molarity(M)

<h3>Further explanation</h3>

According to Arrhenius, Base is a compound which in water releases OH- ions

Electrolytes (acids or bases) with a small degree of ionization are classified as weak electrolytes

If two students, Lydia and Damien, select each bottle of a concentrated weak base, then a guide can be chosen to choose some of the solutions available in the lab :

Base compounds are usually known from their names ending in hydroxide suffixes such as NaOH, sodium hydroxide

The weak base will be partially ionized in water because the ionization degree is close to 0 or less than 1

If there is a Kb value (base ionization constant), then this shows the strength of the base. The greater the value of Kb, the greater the base strength

If there are some weak bases, then Lydia and Damien choose the highest concentration, usually indicated by the value of Molarity (M)

Because no choice solution is included, the weak base example is:

Ammonia (NH₃)

Aluminum hydroxide (Al (OH)₃)

Copper (II) hydroxide Cu (OH)₂

Mercury (II) hydroxide Hg (OH)₂

The human body produces motion by changing chemical energy into mechanical energy. What happens to the energy

Fantom [35]

Answer:

When you eat food, your body can use the chemical energy in the food to make your muscles move so you can breathe, walk, run, jump, lift things, and do all the other things you need to do to live. The chemical energy in the food gets changed into the mechanical energy of moving muscles.

The ____ are new substances that are created following a chemical reactions

amm1812

Answer : The Product are the new substances that are created following a chemical reactions.

Explanation :

Chemical reaction : A chemical reaction occur when two or more reactants react to form a new substance.

Reactant : A substance that is involved in a chemical reaction.

Product : A new substance that is formed in a chemical reaction.

For example : $A+B\rightarrow AB$

In this, A and B are the reactants and AB is the product.

Therefore, the answer is Product.
