SCORPION-xisa [38]

Answer:

16Ag + 2C2 ---> 4 Ag4C

Explanation:

Ag + C2 ----> AgC2

The valence of Ag is one

Valence of Carbon is four

A balanced equation would be

Covalent compounds occur------

irga5000 [103]

Answer:

Only between nonmetals

Explanation:

Covalent compounds are compounds that are formed as a result of covalent bonding between nonmetal atoms.
Covalent compounds occur only between non metals, where atoms of the nonmetals involved join to form a covalent bond as a result of sharing of electrons.
<u><em>Electrons shared during the formation of covalent bond, may be from one atom involved or each atom contributing equally to the bond formation.</em></u>
An example of covalent compounds include, phosphorus (v) oxide, methane, water, CO2,etc.

***BRAINLIEST ASNWERRR***<br>How many grams are in 34.2 moles of Lithium (Li)?

Step2247 [10]

Mass of Li = 237.38 g

<h3>Further explanation</h3>

The mole itself is the number of particles contained in a substance amounting to 6.02.10²³

$\large {\boxed {\boxed {\bold {mol = \frac {mass} {molar \: mass}}}}$

<h3>Known</h3>

Moles of Li = 34.2

Molar mass(MW) of Li = 6.941 g/mol

then mass of Lithium (Li) :

$\tt mol=\dfrac{mass}{MW}\\\\mass=mol\times MW\\\\mass=34.2\times 6,941~g/mol\\\\mass=\boxed{\bold{237.38~g}}$

What can you tell about element hydrogen

Vikki [24]

Answer:

At standard temperature and pressure, hydrogen is a colorless, odorless, tasteless, non-toxic, nonmetallic, highly combustible diatomic gas with the molecular formula H2. Since hydrogen readily forms covalent compounds with most nonmetallic elements, most of the hydrogen on Earth exists in molecular forms such as water
