Answer:

NaOH: 22.99 + 16.00 + 1.008 = 40.00 g/mol

H₂O: 2(1.008) + 16.00 = 18.02 g/mol

C₆H₁₂O₆: 6(12.01) + 12(1.008) + 6(16.00) = 180.2 g/mol

CaSO₄: 40.08 + 32.06 + 4(16.00) = 136.1 g/mol

Mg₃(PO₄)₂: 3(24.33) + 2(30.97) + 8(16.00) = 262.9 g/mol

The numbers I added up are the atomic numbers you can find on the periodic table. Multiply the atomic numbers by however many atoms of a element you have.

Urgent!! A chemist measured 5.2 g copper(II) bromide tetrahydrate (CuBr2•4(H2O)). How many moles were measured out? Answer in un

bezimeni [28]

The moles which were measured out is calculated using the following formula

moles = mass/molar mass

molar mass of CuBr2.4H20 = 63.5 Cu + ( 2 x79.9) br + ( 18 x4_) h20 = 295.3 g/mol

moles is therefore= 5.2 g/ 295.3 g/mol= 0.0176 moles

How does weathering change rock and minerals

Phantasy [73]

Weathering is the process of breaking large rocks and boulders into much smaller ones. Weathering can be brought about by wind and water mostly. Sometimes even biological forces account for some types of weathering.

A sealed container at 25oC contains a gas at a pressure of 104 kPa. What is the pressure of the gas when it is heated to 225oC?

seropon [69]

Answer:

174 kPa

Explanation:

Given that,

Initial temperature, T₁ = 25° C = 25+273 = 298 K

Final temperature, T₂ = 225°C = 225 + 273 = 498 K

Initial pressure, P₁ = 104 kPa
