Answer:
Mass = 824.57 g
Explanation:
Given data:
Mass of bromine = ?
Number of moles of bromine = 5.16 mol
Solution:
Formula:
Mass = number of moles × molar mass
Molar mass of bromine = 159.8 g/mol
by putting values,
Mass = 5.16 mol × 159.8 g/mol
Mass = 824.57 g
The balanced reaction that describes the reaction between sulfuric and sodium hydroxide to produce sodium sulfate and water is expressed <span>H2SO4 + 2NaOH → 2H2O + Na2SO4. When 65.5 grams of sodium hydroxide reacts with excess sulfur, we need first to convert the mass to moles and multiply by stoich ratio 2/2 or 1. Hence the moles is multiplied to the molar mass of water. The final answer is 29.475 grams water.</span>
Answer:
A. sulfur dioxide
Explanation:
The volcanoes are able to influence the global climate both on the short term and on the long term. The end result can be either cooling off of the climate, or warming up of it, depending on what type of gasses are the volcanoes going to release in the atmosphere, as well as how much of them. The sulfur dioxide is a gas that is released by the volcanoes that causes cooling off of the climate. This gas is going through conversion and becomes sulfuric acid, and it is able to restrict the amount of sunlight reaching the surface of the Earth, as well as increasing the reflective properties of the atmosphere, resulting in a few years of significant cooling of the climate.
Answer:
6.1 ×10^-19 J
Explanation:
From E= hc/λ
h= planks constant = 6.6×10^-34 Js
c= speed of light = 3×10^8 ms^1
λ= wavelength = 325 nm
E= 6.6 × 10^-34 × 3×10^8/325 × 10^-9
E= 0.061 × 10^ -17 J
E= 6.1 ×10^-19 J
