Yes, Sharpies contain volatile solvents—and when inhaled these solvents can produce a "high." The effects of inhalants (including Sharpies) can be similar to those of alcohol and include slurred speech, lack of coordination, euphoria, and dizziness.
Answer:
4 C2H5 + 13 O2 -> 8 CO2 + 10 H2O
Explanation:
What I do is I make a chart of how many elements the product side and reactant sides have:
Reactants-
2 C
5 H
2 O
Products-
1 C
3 O
2 H
It's easier to see how many coefficients are needed for the reaction to be balanced then. Hope this helped.
4.98 x 10^3 would be 4980.
Answer:
0.1 M
Explanation:
Molarity = number of moles / litres of solution.
4 g of calcium bromide = 0.02 mol
(found by dividing 4 g by the atomic mass of CaBr2, which is 199.886)
200 mL of solution = 0.2 litres
Molarity = 0.02 mol / 0.2 L = 0.1 M
THE EXTRACTION OF METALS FROM THEIR RESPECTIVE ORES IS KNOWN AS METALLURGY.
THE DIFFERENT PROCESS ARE :- ROASTING, CALCINATION, FROTH FLOTATION AND MGNETIC SEPARATION.
