Chemistry
1 answer:
castortr0y [4]3 years ago
6 0

Answer:

2Na+Cl2 -> 2NaCl

Explanation:

1Na+1Cl 2 -> 1NaCl (i'm assuming they want you to balance it so ill start with 1)

Na = 1

Cl = 2 (it is 2 because it is Cl2, meaning that there are 2; but remember that you cannot change this number only coefficients)

Na = 1

Cl = 1

We need to have 2 Cl on the product side

1Na+1Cl 2 -> 2NaCl

Now we need 2 Na on the reactants side

The final equation is

2Na+Cl2 -> 2NaCl

Now it is balanced

Na = 2

Cl = 2

--

Na = 2

Cl = 2

In pea plants, yellow seeds are dominant to green seeds. A heterozygous yellow-
san4es73 [151]

Answer:

The phenotypic percentage of having yellow or green seeds is 50% for having either of the two colours

Explanation:

The crossing to determine the offsprings is shown in the image attached where we have two green (Yy) seeds and two yellow (yy) seeds as offsprings.

Thus, <u>the phenotypic percentage of having yellow or green seeds is 50% for having either of the two colours</u>.

Note, the dominant allele is "Y" while the recessive allele is "y". Thus, Yy would produce a yellow colour while yy would produce a green colour (as both mentioned in the question).

Also note that phenotype describes the outward properties/characteristics of an individual.

How many grams are in 9.97 moles of Be(NO3)2?<br> Use two digits past the decimal for all values.
Simora [160]

Answer:

1,869.97 grams of Be(NO3)2

Explanation:

Be(NO3)2 = Be  N2  O6

Be=9.012182g/mole

N2=28.0134g/mole

O6=96g/mole

therefore Be(NO3)2 gives you 187.56g in one mole

so 9.97 moles means there is 9.97 times more

9.97mole Be(NO3)2 * 187.56g Be(NO3)2/1mole Be(NO3)2 = 1,869.97g of Be(NO3)2
