Is the equation above balanced or unbalanced? Explain? Worth 55 points.

Answers

Answer:

For me, it is balanced

Explanation:

Because the amount of element Zn reaction is equal the production. Also as the amount of Hydrogen and Chloride in the reaction and the production are equal.

Balanced even though it is formed differently on each side they are the same. When counting the coefficient in front of it they are still the same.

How do you determine the charge of an isotope?

Answers

Answer:

If the protons in the atom outnumber the  electrons, the isotope has more positive charges than negative charges but If the number of electrons exceeds the number of protons, the ion charge will be negative.

Explanation:

The charge of an isotope is defined by how many more protons there are than electrons.

Or the other way around.

For example if there are 4 protons and 2 electrons, the ion charge is +2 because there are more protons.

If there are 4 electrons and 2 protons, the ion charge is -2 because there are more electrons.

What do a hypothesis and scientific law?

Answers

Answer:

If you mean "What is a hypothesis and the scientific law?" than hypothesis means a supposition or proposed explanation made on the basis of limited evidence as a starting point for further investigation and scientific laws or laws of science, are statements, based on repeated experiments or observations, that describe or predict a range of natural phenomena. The term law has diverse usage in many cases across all fields of natural science.

Answer:

If you mean "What do hypothesis and scientific law have in common" than a hypothesis is a limited explanation of a phenomenon; a scientific theory is an in-depth explanation of the observed phenomenon. A law is a statement about an observed phenomenon or a unifying concept.

calculate the mass of 3.011×10^24 molecules of water​...................... plzz i need it asap plzz help me plzz

Answers

Answer:

90.10 g

Explanation:

Step 1: Given data

Number of molecules of water: 3.011 × 10²⁴ molecules

Step 2: Calculate the moles corresponding to 3.011 × 10²⁴ molecules of water

We will use Avogadro's number: there are 6.022 × 10²³ molecules of water in 1 mole of molecules of water.

3.011 × 10²⁴ molecules × (1 mol/6.022 × 10²³ molecules) = 5.000 mol

Step 3: Calculate the mass corresponding to 5.000 moles of water

The molar mass of water is 18.02 g/mol.

5.000 mol × 18.02 g/mol = 90.10 g

What is the density of 19 milliliters of a liquid substance with a mass of 6.05 grams?

Answers

Answer:

The answer is

0.32 g/mL

Explanation:

The density of a substance can be found by using the formula

[tex]density = \frac{mass}{volume} [/tex]

From the question

mass = 6.05 g

volume = 19 mL

The density of the substance is

[tex]density = \frac{6.05}{19} \\ = 0.3184210526...[/tex]

We have the final answer as

0.32 g/mL
