Answer:

Yes, the formed product is calcium nitride, $Ca_3N_2$ .

Explanation:

Hello,

In this case, the answer is yes, since nitrogen in gaseous state is able to react with calcium in solid state to form calcium nitride as shown below:

$N_2+Ca\rightarrow Ca_3N_2$

This is possible since calcium losses two electrons and nitrogen gains three electrons to remain positively and negatively charged respectively, forming the aforementioned ionic compound.

Best regards.

Daffodils are the most carefree of all spring flowers. ... Daffodil flowers come in many different shapes, sizes, and color combinations. The American Daffodil Society classifies daffodils by their flower shape, and there are officially 13 different classifications.

Explanation:

the small one: they grow from fall-planted bulbs and bloom in spring. The size of a dwarf daffodil depends on the variety, but generally, they grow 4 to 6 inches (10 to 15 cm.)

and i can't find the medium size, sorry

How many grams of nano3 would you add to 500g of h2o in order to prepare a solution that is 0.500 molal in nano3?

VARVARA [1.3K]

When the concentration is expressed in molality, it is expressed in moles of solute per kilogram of solvent. Since we are given the mass of the solvent, which is water, we can compute for the moles of solute NaNO3.

0.5 m = x mol NaNO3/0.5 kg water
x = 0.25 mol NaNO3

Since the molar mass of NaNO3 is 85 g/mol, the mass is

0.25 mol * 85 g/mol = 21.25 grams NaNO3 needed

Given the speed of light as 3.0 × 108 m/s, calculate the wavelength of the electromagnetic

kupik [55]

Answer:

The answer is

$\huge 4.054 \times {10}^{ - 5} \: m \\$

Explanation:

The wavelength of the electromagnetic

radiation can be found by using the formula

$\lambda = \frac{c}{f} \\$

f is the frequency

c is the speed of light

From the question we have

$\lambda = \frac{3.0 \times {10}^{8} }{7.4 \times {10}^{12} } \\$

We have the final answer as

$4.054 \times {10}^{ - 5} \: m$

Hope this helps you

Explain why atomic radius decreases as you move to the right across a period for main-group elements but not for transition elem

Korolek [52]

Atomic radius decreases across a period because valence electrons are being added to the same energy level at the same time the nucleus is increasing in protons. The increase in nuclear charge attracts the electrons more strongly, pulling them closer to the nucleus.
