Answer:
Tantalium (Ta) is found uncombined in nature. It is found in coloumbite-tantalite. Tantalium also comes as a result of Mining. It is separated from others by Electrolysis.
Osmium comes when there is a reaction of Nickel refining as by-product. It is rare element which is found naturally as a free element. It is also found naturally in Alloys with copper and nickel.
Rhodium is obtained as the by-product of Copper as well as Nickel refining.
Answer:
2 ?
Explanation:
(Molar mass of S2Cl2 = 135.036 g/mol)
Eq. wt. of S in S2
Cl
2
= 2×35.5
2×32×35.5 =32g
Eq. wt. of S in SCl
2 =
2×35.5
32×35.5 =16g
So, their ratio is 2.
Answer:
Multiply 1.25 by 0.04 and divide the result obtained by 1,000
Explanation:
Given: [1 gram = 0.04 ounce, 1 liter = 1,000 milliliter]
1.25 x 0.04 = 0.05 oz
Therefore, 0.05 per 1,000 milliliter
0.05 ÷ 1,000 = 0.00005 oz
Therefore, the density of the gas is 0.00005 oz/mL
Hope this helps! :)
The metals are found on the bottom left of the table, while the nonmetals are found at the top right. These elements are separated by a 'band' of semimetals
