Answer:
Both metals and non metals.
Explanation:
The correct formula of baking soda is NaHCO₃,
An element is considered to be metal if it is able to give electron easily due to very low ionization energy.
A non metal is ready to accept electron easily due to high electron affinity.
In sodium bicarbonate :
Na: Sodium : metal
H : Hydrogen: non metal (although placed with first group, alkali metals, in the periodic table as it readily loses electron like metals)
C: Carbon: Non metal
O : Oxygen : Non metal.
So the compound contains both metals and non metals.
Answer : The volume of the resulting solution will be 0.4999 L.
Explanation : As the two molar concentration of the

solution are given and one of the volume concentration needs to be found.
So, according to the formula :-

And here if we consider

as 0.1718 L moles and

as 0.3556 moles then we need to find

as

is given as 0.1222 moles.
Hence on solving the formula we get,

= (0.1718 X 0.3556) / 0.1222 = 0.4999 L

Answer:

Explanation:
We are asked to find the specific heat capacity of a liquid. We are given the heat added, the mass, and the change in temperature, so we will use the following formula.

The heat added (q) is 47.1 Joules. The mass (m) of the liquid is 14.0 grams. The specific heat (c) is unknown. The change in temperature (ΔT) is 1.80 °C.
- q= 47.1 J
- m= 14.0 g
- ΔT= 1.80 °C
Substitute these values into the formula.

Multiply the 2 numbers in parentheses on the right side of the equation.


We are solving for the heat capacity of the liquid, so we must isolate the variable c. It is being multiplied by 25.2 grams * degrees Celsius. The inverse operation of multiplication is division, so we divide both sides of the equation by (25.2 g * °C).



The original measurements of heat, mass, and temperature all have 3 significant figures, so our answer must have the same. For the number we found that is the hundredth place. The 9 in the thousandth place to the right tells us to round the 6 up to a 7.

The heat capacity of the liquid is approximately 1.87 J/g°C.
