Wave Parameters: Wavelength, Amplitude, Period, Frequency ... Speed and Wavelength. ... But, the speed of a wave has nothing to do with the amplitude of its crests and troughs. Speed is measured by the distance the wave travels in a certain amount of time. Specifically, it's measured in meters per second.

If you want to melt ice into liquid water, does the ice absorbs heat or release heat? Is this endothermic or exothermic?

kherson [118]

Answer:

Endothermic

Explanation:

This would be an endothermic reaction, due to the fact that the water would be signifigantly warmer then the ice cube, which causes it to melt.

How many moles are present in 63.80L of oxygen gas, O2?

matrenka [14]

Answer:

2.85moles of oxygen gas

Explanation:

Given parameters:

Volume of oxygen gas = 63.8L

Unknown:

Number of moles = ?

Solution:

We assume that the gas is under standard temperature and pressure. To find the number of moles, use the expression below:

1 mole of a gas at STP occupies a volume of 22.4L

So;

63.8L of oxygen gas will take up a volume of

$\frac{63.8}{22.4}$ = 2.85moles of oxygen gas

Determine how many grams of precipitate (solid) will form when 621 g of magnesium

kakasveta [241]

Answer:

2,981g

Explanation:

Firstly, we need to find the number of moles of MgCl that we have by using the formula: mass = No. Moles x Molar Mass, which we can rearrange so that we are solving for no. moles:

No. Moles = mass / Molar Mass

We are given a mass of 621g, and we can calculate the molar mass of MgCl by adding the two molar masses together: 24.31+35.45 = 59.76

Now we can calculate number of moles by substituting these values into the formula:

n = 621 / 59.76

No. moles = 10.4

Now we can use the co-efficients in the formula to tell us how many moles of AgCl will be formed. The coefficient of MgCl is 1, and the coefficient of AgCl is 2. This means that every 1 mol of MgCl will form 2 moles of AgCl. So, to find the no. moles of AgCl, we multiply our no. moles by 2:

10.4 x 2 = 20.8 moles

Finally we convert this back into mass by multiplying the no. moles by the Molar mass of AgCl:

m = 20.8 x (107.87+35.45)

m = 2,981g

Consider the Lewis structure for glycine, the simplest amino acid: (a) What are the approximate bond angles about each of the tw

UkoKoshka [18]

Each carbon is tetrahedrally planar and has three sections, making all bond angles in (a) 120°.(b) hybridization with sp2.(c) If a double bond is present in the compounds, one of the bonds is a sigma connection and the other a pi bond.

<h3>What is an example of an amino acid?</h3>

A basic amino group (NH2), a carboxyl group group (COOH), and an organic Aromatic rings that really is specific to each amino acid make up an amino acid, an organic molecule.

<h3>Which five amino acids are there?</h3>

You must obtain the nine essential amino acids cytochrome c, isoleucine, hcl, lysine, methionine, phenylalanine, alanine, tryptophan, and valine through your food.They are essential for several bodily processes, such as protein biosynthesis, tissue regeneration, and nutrient uptake.
