A)How many moles of O2 are required for the complete combustion of 2.2 g of C3H8 to form CO2 and H2O?
Oksana_A [137]
<span>A)How many moles of O2 are required for the complete combustion of 2.2 g of C3H8 to form CO2 and H2O?

C3H8 + 5O2 = 3CO2 + 4H2O

2.2 g C3H8 ( 1 mol / 44.11 mol ) ( 5 mol O2 / 1 mol C3H8) = 0.25 mol O2


b)A 65.25 g sample of CuSO4•5H2O (M = 249.7) is dissolved in enough water to make 0.800 L of solution. What volume of this solution must be diluted with water to make 1.00 L of 0.100 M CuSO4?

M1V1 = M2V2
[65.25 ( 1 / 249.7 )/ 0.800 L] (V1)= 0.100  (1.00 L)
V1 = 0.31 L or 310 mL </span>

State one advantage of building a space station in orbit instead of sending it all up in one piece.
Anit [1.1K]
Building a space station in orbit is a safety measure. If a rocket fails to bring up the entire space station in one piece it would be extremely expensive to build a new one. Bringing it up in multiple places ensures less money would be lost if the rocket fails.

What are the products of the chemical reaction between solutions of sodium bromide with a solution of silver nitrate?
iren2701 [21]

Answer : The products of the chemical reaction are, NaNO_3 and AgBr

Explanation :

Balanced chemical reaction : It is defined as the reaction in which the number of atoms of individual elements present on reactant side must be equal to the product side.

When sodium bromide react with silver nitrate then it react to give sodium nitrate and silver bromide as a product.

The balanced chemical reaction will be:

NaBr+AgNO_3\rightarrow NaNO_3+AgBr

The given reaction is a double-displacement reaction in which the cation of two reactants molecule exchange their places to give two different products.

The species present on the left side of the right arrow is the reactant and the species present on the right side of the right arrow is the product.

In the balanced chemical reaction,

NaBr and AgNO_3 are reactants.

NaNO_3 and AgBr are products.

Hence, the products of the chemical reaction are, NaNO_3 and AgBr
