Answer:

9.2x10²g

Explanation:

Data obtained from the question include the following:

Density = 0.92g/ml

Volume = 1L = 1 x 1000 = 1000mL

Mass =..?

Density is simply defined as the mass of the substance per unit volume of the substance. Mathematically it can be represented as:

Density = Mass /volume.

Mass = Density x volume

Mass = 0.92 x 1000

Mass = 9.2x10²g.

Therefore, 1L of olive will weigh 9.2x10²g.

Write the NET IONIC EQUATION between zinc and hydrochloric acid.

makkiz [27]

Answer:

$Zn_{(s)}+2H^{+}_{(aq)}\rightarrow Zn^{2+}_{(aq)}+H_2_{(g)}$

Explanation:

Zinc reacts with hydrochloric acid to given zinc chloride and hydrogen gas. The liberation of the hydrogen gas can be confirmed by burning the gas. If the gas burns with pop sound, it means it is hydrogen gas

The molecular chemical equation for the reaction is:

$Zn_{(s)}+2HCl_{(aq)}\rightarrow ZnCl_2_{(aq)}+H_2_{(g)}$

The total ionic equation is:

$Zn_{(s)}+2H^{+}_{(aq)}+2Cl^{-}_{(aq)}\rightarrow Zn^{2+}_{(aq)}+2Cl^{-}_{(aq)}+H_2_{(g)}$

The net ionic equation is:

$Zn_{(s)}+2H^{+}_{(aq)}\rightarrow Zn^{2+}_{(aq)}+H_2_{(g)}$

How many grams of sugar must be dissolved in 150 ML of water to make a solution that has a concern traction of .6 g/ml

grandymaker [24]

Hey there!:

Density = 0.6 g/mL

Volume = 150 mL

Mass = ?

therefore:

D = m / V

0.6 = m / 150

m = 0.6 x 150

m = 90.0 g of sugar

Hope this helps!

A sealed vessel containg helium, chlorine and fluorine has a total pressure of 205 kpa and partial pressures of 15 kpa for chlor

MrRa [10]

According to Dalton's law of partial pressure

The total pressure of a mixture of ideal gases is sum of the partial pressures of each gas present in the mixture

So if we know the partial pressure of all the gases we can determine the total pressure of the mxiture by adding all of them.

Thus

Ptotal = PCl2 + PF2 + PHe

Thus

Partial pressure of helium = 205 - ( 89 + 15) = 101 kPa
