Answer:

The difference in temperature causes differences in air pressure between the two spots. ... This causes the jet stream to dip farther south and the winds to blow stronger on either side of the jet stream in winter. The jet stream separates the very cold air mass at higher latitudes from the warmer air mass equatorward.

You can practice converting between the mass of a solution and mass of solute when the mass percent concentration of a solution

Ostrovityanka [42]

Answer:

145 grams of a 0.480 % KCN solution contains 697 mg of KCN.

Explanation:

w/w % : The percentage mass or fraction is mass of the of solute present in 100 grams of the solution.

$w/w\%=\frac{\text{Mass of solute}}{\text{Mass of solution}}\times 100$

given = w/w% = 0.480 %

Mass of solute that KCN = 697 mg = 0.697 g

(1 mg = 0.001 g)

Mass of the solution = ? = x

$0.480\%=\frac{0.697 g}{x}\times 100$

$x=\frac{0.697 g}{0.480}\times 100$

x = 145.21 g ≈ 145 g

145 grams of a 0.480 % KCN solution contains 697 mg of KCN.

If you had an object with a mass of 76g and a volume of 22 ml, what is its density? If you cut this object in half, what would b

V125BC [204]

D = M/V = 76g / 22ml = 3.4g/ml

Half ~ D = 38g / 11ml = 3.4g/ml

Even if the object you had was cut in half, it’s density would remain the same.

KatRina [158]

Burning a magnesium ribbon in the air is an addition reaction while heating potassium manganate 7 is a decomposition reaction.

<h3>Addition and decomposition reactions</h3>

Magnesium burns in air to produce magnesium oxide as follows:

$2Mg + O_2 --- > 2MgO$

Potassium manganate 7 burns to produce multiple products as follows:

$2 KMnO_4 --- > K_2MnO_4 + MnO_2(s) + O_2$

Thus, the MgO will be heavier than Mg. On the other hand, $MnO_2$ will be less heavy than $KMnO_4$ .
