Ilya [14]3 years ago
8 0

Answer:

100 cal

Explanation:

Given data:

Mass of carbohydrate = 19 g

Mass of protein = 1 g

Mass of fats = 4 g

Solution:

The average calories content of

Protein 4 cal/g

Carbohydrate 4 cal/g

Fat 9 cal/g

Then,

1 g protein × 4 cal/g =  4 cal

4 g fat × 9 cal/g = 36 cal

19 g carb. × 4 cal/g = 76 cal

               Total calories = 116 cal  

Round to one significant figure = 100 cal

a new weight-loss fad claims that you can reduce your mass simply by traveling to the Moon where gravity is weaker. why is this
Lilit [14]
Your mass can never change no matter where you are since mass is the amount of matter you contain.  By going to the moon, you do become lighter due to the weaker gravity but the amount of matter that you are made of (your mass) does not change.

I hope the helps.  Let me know if anything is unclear.

What is Equilibrium? I’m a little confused on the topic. You’ll get a lot of points if you answer I think.
AleksAgata [21]

Answer:

to put it simply, equilibrium is when two opposing forces balance each other out. one example is boats: you know how the bottom half is curved, and then meets at an edge? they design it like that because of water displacement. by gravity, the water wants to go back to the area taken by the boats mass (the parts where it has sunken into the water), thus preventing the boat from sinking. once the boat is removed, the water returns to the space. most liquids take form of their container.

If I have 7.5 L of a gas in a piston at a pressure of 1.75 atm and compress the gas until its volume is 3.7 L, what will the new
Sergio [31]

Answer:

3.55atm

Explanation:

We will apply Boyle's law formula in solving this problem.

P1V1 = P2V2

And with values given in the question

P1=initial pressure of gas = 1.75atm

V1=initial volume of gas =7.5L

P2=final pressure of gas inside new piston in atm

V2=final volume of gas = 3.7L

We need to find the final pressure

From the equation, P1V1 = P2V2,

We make P2 subject

P2 = (P1V1) / V2

P2 = (1.75×7.5)/3.7

P2=3.55atm

Therefore, the new pressure inside the piston is 3.55atm

Conversion factors are useful in solving problems in which a given measurement must be expressed in
spin [16.1K]

Conversion factors are useful in solving problems in which a given measurement must be expressed in some other units of measure.


Conversion factors
are helpful in solving issues where one unit of measurement needs to be expressed in another. In general, a measurement's numerical value changes when it is multiplied by a conversion factor, while the quantity being measured's real size stays the same.
A conversion factor is a number that is used to multiply or divide one set of units into another. If a conversion is required, it must be done using the correct conversion factor to get an identical value. For instance, 12 inches equals one foot when converting between inches and feet.

What are the steps in naming and determining the formula of ionic compounds?
vredina [299]
If you have to write the chemical formula of a simple, binary ionic compound given the name of the compound, you follow a set of three steps. Let's go through them using magnesium chloride as an example. Write the symbols for the cation and the anion: Mg and Cl. Determine the charge on the cation and anion.
