Answer:

Calcium phosphorous

Explanation:

First, this compound is a mixture of the following elements:

Ca: Calcium

P: Phosphor

Now, both of these elements are united as a binary compound, the metal and a non metal. When we have a binary compound with a metal and non metal, (When the non metal is not hydrogen or oxygen) this usually becomes a salt. A bynary salt. So a binary salt, we should name like this

In this, we should name first the metal and then the non metal with the sufije ous. In this case:

Calcium phosphorous.

Then the name of this salt is that.

A chemist carefully measures the amount of heat needed to raise the temperature of a 894.0g sample of a pure substance from to −
astraxan [27]

Answer:

C = 0.2349 J/ (g °C)

Explanation:

Mass, m = 894.0g

Initial Temperature = −5.8°C

Final Temperature =  17.5°C

Temperature change = 17.5°C - (−5.8°C) = 23.3

Heat, H = 4.90kJ = 4900 J

Specific heat capacit, C = ?

The relationship between these quantities is given by the equation;

H = mCΔT

C = H / mΔT

C = 4900 / (894)(23.3)

C = 0.2349 J/ (g °C)
