The reaction between oxygen, O2, and hydrogen, H2, to produce water can be expressed as,

2H2 + O2 --> 2H2O

The masses of each of the reactants are calculated below.

2H2 = 4(1.01 g) = 4.04 g
O2 = 2(16 g) = 32 g

Given 1.22 grams of oxygen, we determine the mass of hydrogen needed.
(1.22 g O2)(4.04 g H2 / 32 g O2) = 0.154 g of O2

Since there are 1.05 grams of O2 then, the limiting reactant is 1.22 grams of oxygen.

Answer: 1.22 g of oxygen

Why must energy be controlled?

eduard

Answer:

Energy should be saved and controlled as it is better for the environment. Excess use of energy of any kind can be disastrous. For example, a kind of energy is stored in the food. If excess food is consumed and wasted, then the country and other people will have to face consequences of it. Malnutrition will rise.

Another kind of energy is the energy in the fuel. If fuel consumption is not controlled then in the near future the resources for the making of fuel will be depleted.

Suppose you burn a substance in the air (reactants) and produce smoke and ash (products). The law of conservation of mass states

Aleks04 [339]

Answer:

The same as can best fill the space

Explanation:

The law of conservation of mass states that matter cannot be created or destroyed in a chemical reaction. For example, when wood burns, the mass of the soot, ashes, and gases, equals the original mass of the charcoal and the oxygen when it first reacted.

It shows that when wood burns, it combines with oxygen and changes not only to ashes, but also to carbon dioxide and water vapor. The gases float off into the air, leaving behind just the ashes. Suppose you had measured the mass of the wood before it burned and the mass of the ashes after it burned. Also suppose you had been able to measure the oxygen used by the fire and the gases produced by the fire. What would you find? The total mass of matter after the fire would be the same as the total mass of matter before the burning.

Which samples will heat up faster? Explain why

True [87]

In short, I’d say the answer is C.

In solids, the intermolecular force of attraction is very high. Whereas, in liquids the intermolecular force of attraction is somewhat less than solids. ... so when you heat, less amount of heat can free the molecules in liquids than solids and hence they heat faster.

How many grams of water can be produced when 65.5 grams of sodium hydroxide reacts with excess sulfuric acid? Unbalanced equatio

kap26 [50]

The balanced reaction that describes the reaction between sulfuric and sodium hydroxide to produce sodium sulfate and water is expressed H2SO4 + 2NaOH → 2H2O + Na2SO4. When 65.5 grams of sodium hydroxide reacts with excess sulfur, we need first to convert the mass to moles and multiply by stoich ratio 2/2 or 1. Hence the moles is multiplied to the molar mass of water. The final answer is 29.475 grams water.
