how many gallons of water did a truck fill up if it's weight before the fill up was 3547 lbs and afterwards was 4924 lbs?
musickatia [10]

Answer: depending on the method, 138-139 (imperial) gallons, or 626 L

Explanation:

The wt of water is 4924-3547 lb = 1377 lb = 1377/2.2 kg = 626 kg = 626 L

1gallon = 4.5 L (it does where I come from and who still measures things in imperial anyway?) so I guess  that is 139 gallons

or alternatively, I recall from distant childhood, “a pint of water weighs a pound and a quarter” which means 1 gallon = 10 lb, so 1377 lb = ~138 gallons

If a gas is cooled from 315K to 231K and the volume is kept constant, what would the final pressure be if the original pressure
goblinko [34]

Answer:

455.4 mmHg

Explanation:

To solve this problem we can use <em>Gay Lussac's Law</em>, which describe the temperature and pressure of a gas, at constant volume and composition:

  • P₁T₂ =  P₂T₁

In this case:

  • P₁ = 621 mmHg
  • P₂ = ?
  • T₁ = 315 K
  • T₂ = 231 K

We <u>input the data</u>:

  • 621 mmHg * 231 K = P₂ * 315 K

And <u>solve for P₂</u>:

  • P₂ = 455.4 mmHg

which of the following testable questions will provide evidence that elements in the same group have similar properties?
Usimov [2.4K]

The testable question which will provide evidence that elements in the same group have similar properties is valency

<h3>What is the valency?</h3>

In essence, how many electrons are present in their outermost shell.

Valency and Groups in the periodic table, elements are arranged in order of their atomic numbers and hence, the periodic table is a systematic arrangement of elements in an array of vertical columns called Groups and horizontal arrays called Periods.

  • Complete question here:

which of the following testable questions will provide evidence that elements in the same group have similar properties A. Valency B. Orbit C. Group D. Period

Since, the reactive capacities of elements is dependent on the number of electrons on its outermost shell, we can conclude on this note that, Elements in the same group have similar properties.
