Answer:
Explanation:
The hydrostatic pressure is defined as the pressure that is exerted by a fluid at equilibrium at a given point within the fluid, due to the force of gravity, the formula is:
P = ρgh + P₀
Where:
ρ is density (1020kg/m³)
g is gravity (9,8m/s²)
h is depth (150m)
P₀ is the atmspheric pressure (101325 Pa)
Replacing, P = 1'600'725 Pa

Answer:
<h2>The answer is 14.29 %</h2>
Explanation:
The percentage error of a certain measurement can be found by using the formula

From the question
actual density = 0.70 g/mL
error = 0.8 - 0.7 = 0.1
So we have

We have the final answer as
<h3>14.29 %</h3>

For #4 first find the molar mass(M) of copper then use that and the mass (m) n=m/M to find moles(n) using moles and the volumes find the concentration using c=n/V
Answer:
a). Volume is 30 cm³ and it has a indefinite shape.
Volume of the liquid is measured using a conical flask on the right.
c). Drinking water is a homogeneous mixture though it is a compound. And it has a indefinite shape though it takes up shape of a container.

Here we have to determine the formula of the ionic compound formed between a and iodine.
The ionic compounds are those which remains in ionic state in its solution phase. The formula of the compound aF₃ which reveals the element a is trivalent i.e. a³⁺. It will remain in ionic state as follows: aF₃ → a³⁺ + 3F⁻.
As the element a is trivalent thus with iodine also it will combine like fluorine (as both belongs to the same halogen group). The formula of the compound will be aI₃ and it will be ionic in nature. The ions will be aI₃ → a³⁺ + 3I⁻.
Thus the formula of the ionic compound between a and iodine is determined.
