1. What is the density, in g/cm², of a substance weighing 22.2 cg with dimensions of 0.333

Chemistry

RUDIKE [14]2 years ago
7 0
  • Mass=22.2cg=2.22g

Volume:-

\\ \tt\longmapsto 0.333(0.444)(0.555)=0.08cm^3

So

\\ \tt\longmapsto Density=\dfrac{Mass}{Volume}

\\ \tt\longmapsto Density=\dfrac{2.22}{0.08}=27.75g/cm^3

Forces and Motion:Question 1
defon

Answer:

Velocity = 12 km/h

Explanation:

Velocity can be defined as the division between distance traveled and the time it took for that distance to be traveled:

  • Velocity = Distance / Time

With the above information in mind, we can calculate the velocity of the bicycle:

  • Velocity = 18 km / 1.5 h
  • Velocity = 12 km/h

Thus the velocity of the bicycle is 12 kilometers per hour.

Hat is used and produced in glycoloysis?
agasfer [191]

During glycolysis is used glucose, ADP and pyruvate and produce ATP, water and NADH.

<h3>What is glycolysis?</h3>

Glycolysis is the first step of cellular respiration by which glucose is used to generate energy in the form of ATP.

Cellular respiration has three sequential steps, i.e., glycolysis, the Krebs cycle and oxidative phosphorylation.

Glycolysis is the cellular respiration step that generates 2 net high energy ATP molecules and 2 reduced NADH.

In conclusion, glycolysis uses glucose, pyruvate and ADP to generate ATP, water and Nicotinamide adenine dinucleotides (NADH).

A 7.47 g sample of calcium carbonate [CaCO3 (s)] absorbs 85 J of heat, upon which the temperature of the sample increases from 2
Alex_Xolod [135]

Answer:

Specific heat of calcium carbonate(C) = 0.82 (Approx)

Explanation:

Given:

Energy absorbs (q) = 85 J

Change in temperature (Δt) = 34.9 - 21 = 13.9°C  

Mass of calcium carbonate = 7.47 g

Find:

Specific heat of calcium carbonate(C)

Computation:

Specific heat of calcium carbonate(C) = q / m(Δt)

Specific heat of calcium carbonate(C) = 85 / (7.47)(13.9)

Specific heat of calcium carbonate(C) = 85 / 103.833

Specific heat of calcium carbonate(C) = 0.8186

Specific heat of calcium carbonate(C) = 0.82 (Approx)

If a certain gas occupies a volume of 10. L when the applied pressure is 5.0 atm , find the pressure when the gas occupies a vol
lorasvet [3.4K]

Answer:

20L is the new volume

Explanation:

In this case, moles and T° from the gas remain constant. This is the formula we must apply, to solve this:

P₁ . V₁ = P₂ . V₂

5 atm . 10 L = P₂ . 2.5L

P₂ = (5 atm . 10 L) / 2.5L →20L
