The mass of the sample is 84.3 g

<u>Explanation:</u>

We have the formula to find the mass

Q = mCΔT

where

Q denotes the energy absorbed or released

m denotes the mass of the sample

C denotes the Specific heat of sample

Δ T denotes the Temperature change

Q = mCΔT

Rewrite the equation as,

m = Q/ C Δ T

m=24000 J/4.186 J/g°C× ( 69.5 °C-0°C)

m=82.42

m=84.3 (based on the options)

The mass of the sample is 84.3 g

Sodium tends lose a single electron in natural settings. Based on what you know, what are two other elements that tend to do the
Oksi-84 [34.3K]

Answer:

Lithium and Sodium

Explanation:

Losing and electron in natural setting is characterizes of elements in group one. These are elements known as the alkaline earth metals. They are the most electropositive elements on the periodic table.

These elements ionize by losing an electron yin their outermost shell to attain the configuration of the nearest noble gas. These elements are usually found in combined and rarely seen in uncombined state principally due to their very reactive nature.

Sodium naturally would ionize by losing one electron. Other elements capable of this even at a better rate because they are more electropositive are potassium and lithium. Both are also group one alkaline metals
