Bronsted Lowry base is the species that accepts or acquires protons from other species of the reaction. is the Bronsted-Lowry base.
<h3>What is a Bronsted-Lowry base?</h3>
In an acid-base reaction, the element or the compound capable of obtaining a proton or a hydrogen atom is called a Bronsted-Lowry base.
According to the theory, the base will accept proton and acid will donate an electron. The reaction of the acid and base is shown as,
From the reaction, it can be said that bicarbonate is the Bronsted-Lowry base as the number of hydrogen or protons are increasing in the product.
Therefore, option b. is the Bronsted-Lowry base.

To make it easier, assume that we have a total of 100 g of a compound. Hence, we have 58.80g of xenon, 7.166g of oxygen, and 34.04g of fluorine.
Know we will convert each of these masses to moles by using the atomic masses:
58.8/131.3 = 0.45 mole of Xe
7.166/16 = 0.45 mole of O
34.04/19 = 1.79 mole of F
Now, we will divide all the mole numbers by the smallest among them and get the number of atoms in the compound:
Xe = 0.45/0.45 = 1
O = 045/0.45 = 1
F = 1.79/0.45 = 3.98 = 4
So, the empirical formula of the compound XeOF₄
Answer:
The terms used to describe the given process in <em><u>Chemical weathering.</u></em>
Explanation:
Weathering of rock is defined as breaking down of the rock into small pieces.
There are two types pf weathering :
Mechanical weathering : This weathering is due to change in physical parameters : temperature change, pressure change etc.
For example : When water soaked up in cracks or crevices of rocks freezes it expands and physically breaks the rock.
Chemical weathering : This weathering is decomposition of rocks due to action of chemicals.This type of weathering also changes chemical composition of rocks.
For example : when gases like carbon dioxide, sulfur oxide get dissolves in water present in rock to form weak acid which ease up the dissolving of rock in that weak acid.
BIOSPHERE AND LITHOSPHERE INTERACTION
The kinetic energy of a photon can be calculated from the product of the planck's constant and the frequency of the light. In this problem, we are given the wavelength. Frequency and wavelength are related. We do as follows:
E = hv where h is the Plank's constant and v is the frequency (v = speed of light / wavelength )
E = h (speed of light / wavelength)
E = <span>6.63x10^-34 ( 3x10^8 )/ (1.50x10^-7 )
E = 1.326x10^-18 J = 8.26 eV</span>
