You have 1169.6 g of a bleach solution. The percent by mass of the solute sodium hypochlorite, NaOCl, is 3.62%. How many grams o
Aneli [31]

Answer:

Mass of solvent is 1127.3 g

Explanation:

NaOCl → 3.62%

This percent means, that in 100 g of bleach solution, there are 3.62 g of NaOCl. So let's make a rule of three:

100 g of bleach solution have 3.62 g

1169.6 g of bleach solution may have (1169.6  . 3.62) /100 = 42.3 g

42.3 g is the mass of NaOCl in the solution

Mass of solution = Mass of solvent + Mass of solute

1169.6 g = Mass of solvent + 42.3 g

1169.6 g - 42.3 g = Mass of solvent → 1127.3 g

Which of the following does not change the energy of the reactants relative to the activation energy?
creativ13 [48]

Answer:

Adding a catalyst

Explanation:

  • Activation energy is the minimum amount of energy needed to start a chemical reaction
  • A Catalyst is a material that increases the rate of a reaction by lowering the activation energy. In other words, a catalyst act to provide an alternative route for the reaction which has a lower activation energy.

A tropical climate is a wet climate. Consider a city like Bogota, Colombia which has a tropical climate. Does a tropical climate
dlinn [17]

Answer:

No, It will mean lot of rains but not every day

Explanation:

In wet tropical climates, the high clouds trap a lot of heat while balancing incoming and outgoing heat energy. When the number of heat trapping cloud remains very low, then the unstable cool air above the clouds cause lot of rain.

Hence, there will rain frequently but no everyday

“Dry ice” is the solid form of carbon dioxide. Determine the number of mass of CO2 gas in grams that are present in 61.8 L of CO
Fofino [41]

Answer:

Mass  = 121 g

Explanation:

Given data:

Mass in gram of CO₂ = ?

Volume = 61.8 L

Pressure = standard = 1 atm

Temperature = 273.15 K

Solution:

Formula:

PV = nRT

P= Pressure

V = volume

n = number of moles

R = general gas constant = 0.0821 atm.L/ mol.K  

T = temperature in kelvin

1 atm × 61.8 L = n ×0.0821 atm.L/ mol.K   × 273.15 k

61.8 L.atm = 22.42 atm.L/ mol × n

n = 61.8 L.atm /22.42 atm.L/ mol

n = 2.76 mol

Mass in gram:

Mass =  number of moles × molar mass

Mass = 2.76 mol × 44 g/mol

Mass  = 121 g
