Calculate the formula mass for the compound nitrous acid.
kari74 [83]

Answer:

47.01g/mol

Explanation:

The formula of Nitrous acid is HNO₂:

The formula mass of a compound gives the sum of the atomic masses of the elements that makes up a compound.

Atomic mass of H = 1.0079g/mol

                          N = 14.0067g/mol

                          O = 15.9994g/mol

Formula mass of HNO₂ = 1.0079 +  14.0067 + 2(15.9994)

                                        = 1.0079 +  14.0067 +31.9988

                                         = 47.01g/mol

elsic (or silicic) magma a. crystallizes at the highest temperatures. b. is more viscous than mafic magma. c. has approximately
mezya [45]

Answer:

Option (B)

Explanation:

Felsic magma refers to those magma that are comprised of more than 65% of silica content and are highly made up lighter elements like oxygen, silicon,  sodium, aluminum, potassium, and are light-colored in comparison to the basic magma. Due to its high silica content, these are high viscosity magma and flows at a much slower rate. The felsic magma crystallizes at a relatively low-temperature rocks and the rocks that are formed from this type of magma have a specific gravity of less than 3.

Thus, the correct answer is option (B).

The rate of change in distance dicided by time​
ArbitrLikvidat [17]

Answer:

I learnt this from Khan academy you should try it too

Explanation:

Rate of change in position, or speed, is equal to distance traveled divided by time. To solve for time, divide the distance traveled by the rate. For example, if Cole drives his car 45 km per hour and travels a total of 225 km, then he traveled for 225/45 = 5 hours.
