Answer:
Nickle
Explanation:
In statement it is given that the metal "M" has a formula "MCl₂" which means it has a charge of +2 as each Chlorine atom has -1 charge. Therefore, it is cleared that this metal has lost 2 electrons and originally it was carrying 28 electrons.
After that periodic table is concerned and a metal with 28 atomic number was tracked because a neutral atom with 28 electrons must have 28 protons and protons are infact the atomic number.
Hence, in periodic table the metal with 28 atomic number is found to be Nickle.
At constant pressure, temperature is directly proportional to the volume and vise versa. The formula will be
V1/T1 = V2/T2
where V1 and T1 are the initial volume and temperature and V2 and T2 are the final volume and temperature. The temperature is in Kelvin and to convert Celsius to Kelvin add 273.
so, 6.24L/298 = V2/328
=6.87L
Answer:
Use E = h*c / lambda, where h is Planck's constant, c is the speed of light, and lambda is the wavelength.
E = (6.626 * 10^-34 J*s x 3.00 * 10^8 m/s) / (1*10^-6 m) = 1.99 * 10^-19 J
Explanation:
Answer:
true
Explanation:
because the atoms make up the elements which forms the compound
Explanation:
The given reaction equation will be as follows.
Now, number of atoms on reactant side are as follows.
Number of atoms on product side are as follows.
Therefore, this equation is balanced since atoms on both reactant and product sides are equal.
Thus, we can conclude that there is one sulfur atom in the products.
