In the mathematical equation showing that volume (V) divided by temperature (T) remains equal to a constant (k), volume and temp

erature are _______________ proportional
Chemistry
1 answer:
NARA [144]3 years ago
7 0

Answer:

Directly  

Explanation:

\dfrac{V}{T} = k

If V increases, then T must also increase to keep the same ratio.

If V decreases, then T must also decrease to keep the same ratio.

V and T are directly proportional, because a change in one always causes a change in the other and the changes are in the same ratio. The constant k is called the proportionality constant.

A 2.36-gram sample of NaHCO3 was completely decomposed in an experiment.
enyata [817]

Answer:

Explanation:

a) The mass of the reactants is 2.36 grams, and the mass of the products is 1.57 grams plus the mass of the carbonic acid. Thus, using the law of conservation of mass, we get the mass of the carbonic acid is 2.36 - 1.57 =  0.79 grams.

b) The gram-formula mass of sodium bicarbonate is 84.006 g/mol, meaning that 2.36/84.006 = 0.028 moles were consumed. Thus, this means that in theory, 0.014 moles of carbonic acid should have been produced, which would have a mass of (0.014)(62.024)=0.868 grams. Thus, the percentage yield is (0.79)/(0.868) * 100 = 91%

IF ANSWER I WILL GIVE BRAINLESS
vovikov84 [41]

Answer:

Answer 9 - 100 joules energy was at the producer level

Answer 10 - Remaining energy is used in metabolism

Explanation:

Answer 9

The energy at each trophic level is only 10% of the energy at its previous trophic level.

The energy at producer level is X

10 % of X = 10 Joules

\frac{10}{100} * X = 10\\X = 100Joules

Answer 10

Because the remaining 90% energy is utilized by the producer for its metabolism

1. Calculate the momentum of a 1,500 kg car traveling at 6 m/s.
ziro4ka [17]

Answer:

1.9000kgm/s

2.258,000kgm/s

Explanation:

1.Momentum is given as the product of mass by velocity of an object.

Momentum,p=mv

m=1,500kh, v=6m/s

p=1500*6\\p=9000kgm/s

2.Momentum,p=mv

m=7800kg, v=30m/s

p_1=7800*30\\p_1=234,000kgm/s\\

new mass=7800+800=8600

As mass is increased, so does the resultant velocity as mass is directly proportional to velocity.

p_2=8600*30\\p_2=258,000kgm/s
