3/4 or 4/4 would be the answer because if you use 1/4 out of 4/4 you would either have an answer of 3/4, 4/4 or 1. The 1 because 4/4 is equal to 1.

The absolute temperature of a gas is increased four times while maintaining a constant volume. What happens to the
weqwewe [10]

Answer:

The pressure increases by a factor of four.

Explanation:

Let's consider a gas at a given temperature and pressure (T₁, P₁). The absolute temperature of a gas is increased four times (T₂ = 4 T₁) while maintaining a constant volume. We can assess the effect on the pressure (P₂) by using Gay Lussac's law.

P₁/T₁ = P₂/T₂

P₂ = P₁ × T₂/T₁

P₂ = P₁ × 4 T₁/T₁

P₂ = 4 P₁

The pressure increases by a factor of four.

What is the mass of 4.2kg gold when it's transferred to a planet having twice the gravity of earth
rjkz [21]

Answer:

The only relationship is that the larger the mass of an object the more gravitational force it has. So... something that has more mass has more gravity. The mass of 4.2kg of gold when transferred to this new planet is still 4.2kg. However, the WEIGHT (not mass) is now doubled to 8.4kg. Mass is constant it is how much matter something is made up of. Weight depends on the gravitational force. Moreover, I would look at other answers too (I'm not entirely confident of saying that the weight is 8.4kg since I don't have any gravitational equations in front of me it just sounds logical).

Phenolphthalein is an indicator that turns from colorless (acidic form) to magenta (basic form) and has a pKa of 9.40. What is t
frosja888 [35]

Answer:

40:1  is the ratio of the magenta phenolphthalein concentration to the colorless phenolphthalein concentration.

Explanation:

To calculate the pH of acidic buffer, we use the equation given by Henderson Hasselbalch:

pH=pK_a+\log(\frac{[salt]}{[acid]})

pH=pK_a+\log(\frac{[magenta(Php)]}{[Php]})

We are given:

pK_a = negative logarithm of acid dissociation constant of phenolphthalein = 9.40

[magenta(Php)] = concentration of magenta phenolphthalein

[Php] = concentration of colorless phenolphthalein

pH = 11

Putting values in above equation, we get:

11=9.40+\log(\frac{[magenta(Php)]}{[Php]})

\log(\frac{[magenta(Php)]}{[Php]})=11-9.40=1.6

\frac{[magenta(Php)]}{[Php]}=10^{1.6}=39.81 :1 \approx 40:1

40:1  is the ratio of the magenta phenolphthalein concentration to the colorless phenolphthalein concentration.
