Answer:

2.0 g CaCO₃

Explanation:

We are given molarity and volume, so we can find moles since molarity is moles of solute divided by volume of solution in liters. We can then convert from moles to grams using the molar mass of CaCO₃.

2 L x 0.010 mol/1 L x 100.0869 g/1 mol = 2.0 g CaCO₃ (two significant figures)

What energy transfer is occurring when a plant uses energy from the sun to make sugar in fruit? Radiant energy is converted to n

IrinaK [193]

The right answer is Radiant energy is converted to stored chemical energy.

Photosynthesis aims to create energy (in the form of carbohydrate) from the light energy from the sun.

Solar energy is used to oxidize water and reduce carbon dioxide to synthesize organic substances (carbohydrates). This phenomenon occurs in chloroplasts, a plant-specific organelle, at the level of the thylakoid membranes where photosystems I and II and cytochromes are located.

mezya [45]

The given question is incomplete. The complete question is:

A chemist prepares a solution of barium chloride by measuring out 110 g of barium chloride into a 440 ml volumetric flask and filling the flask to the mark with water. Calculate the concentration in mole per liter of the chemist's barium chloride solution. Round your answer to 3 significant digits.

Answer: Concentration of the chemist's barium chloride solution is 1.20 mol/L

Explanation:

Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution.

$Molarity=\frac{n\times }{V_s}$

where,

n = moles of solute

$V_s$ = volume of solution in L

moles of $BaCl_2$ (solute) = $\frac{\text {given mass}}{\text {Molar Mass}}=\frac{110g}{208g/mol}=0.529mol$

Now put all the given values in the formula of molality, we get

$Molality=\frac{0.529\times 1000}{440ml}=1.20mole/L$

Therefore, the molarity of solution is 1.20 mol/L

Can ocean currents modify climate

JulijaS [17]

Ocean currents act much like a conveyer belt, transporting warm water and precipitation from the equator toward the poles and cold water from the poles back to the tropics. Thus, currents regulate global climate, helping to counteract the uneven distribution of solar radiation reaching Earth's surface.
