In what form does the sun's energy arrive on Earth?The physical characteristics of two large predatory animal species are shown

in the table below.
Physical Characteristics
Species Characteristics
X Short canine teeth, small prey size
Y 1-foot-long canine teeth, large prey size
Which species will most likely survive if the prey population in the area decreases?

Species X because it is difficult to bring down a small prey
Species X because short canines are less likely to break
Species Y because long canines are less likely to break
Species Y because it is easy to bring down a large prey

Which of the following shows 3x + 15 + 6x – 7 + y in simplest terms?
prisoha [69]

Answer:

9x+y+8

Explanation:

We know this because you add 3x and 6x to get 9x

then we only have one y so put y by itself then subtract 15 and y which gets us 8

When solutions of sodium sulfide and copper(ii) sulfate are mixed, a precipitate of copper(ii) sulfide is formed. what is the ne
ozzi

When solutions of sodium sulfide and copper(ii) sulfate are mixed, a precipitate of copper(ii) sulfide is formed. The net ionic equation for this reaction is Cu⁺² (aq) + S⁻² (aq) → CuS (s).

<h3>What is Balanced Chemical Equation ?</h3>

The balanced chemical equation is the equation in which the number of atoms on the reactant side is equal to the number of atoms on the product side in an equation.

Now first write the balanced chemical equation

CuSO₄ (aq) + Na₂S (aq)  → CuS(s) + Na₂SO₄ (aq)

Now write the net ionic equation

Cu⁺² (aq) + SO₄⁻² (aq) + 2Na⁺ (aq) + S⁻² (aq) → CuS (s) + 2Na⁺ + SO₄⁻² (aq)

So the net ionic equation is

Cu⁺² (aq) + S⁻² (aq) → CuS (s)

Thus from the above conclusion we can say that When solutions of sodium sulfide and copper(ii) sulfate are mixed, a precipitate of copper(ii) sulfide is formed. The net ionic equation for this reaction is Cu⁺² (aq) + S⁻² (aq) → CuS (s).

How many grams of NaCl are needed in order to make a liter of a 2.00 M NaCl solution? O 58.4 g O 117 g O 2.00 g​
vitfil [10]

Answer:

B.) 117 g

Explanation:

(Step 1)

To find the mass, you need to first find the moles of NaCl using the molarity  ratio.

Molarity = moles / volume (L)

2.00 M = moles / 1.0 L

2.00 = moles

(Step 2)

Now that you know the moles, you can convert it to grams using the molar mass.

Molar Mass (NaCl): 22.990 g/mol + 35.453 g/mol

Molar Mass (NaCl): 58.443 g/mol

2.00 moles NaCl          58.443 g
---------------------------  x  -----------------  =  117 g NaCl
                                        1 mole
