Answer:
compound
Explanation:
When two distinct elements are chemically combined—i.e., chemical bonds form between their atoms—the result is called a chemical compound. Most elements on Earth bond with other elements to form chemical compounds, such as sodium (Na) and Chloride (Cl), which combine to form table salt (NaCl).
Answer:
108.76 amu is the mass of 109Ag
Explanation:
The formula for the calculation of the average atomic mass is:
Given that:
Since the element has only 2 isotopes, so the let the percentage of first be x and the second is 100 -x.
For first isotope, 109Ag:
% = 51.82 %
Mass = x amu
For second isotope, 107Ag:
% = 100 - x
= 100 - 51.82 % = 48.18 %
Mass = 106.905 amu
Given, Average Mass = 107.868 amu
Thus,
Solving for x, we get that:
x = 108.76 amu
<u>108.76 amu is the mass of 109Ag</u>
Answer:
The left and right hemispheres of the cerebrum are connected by the Corpus Collosum.
Explanation:
The corpus collosum is a thick band of neurons that divides the cerebral cortex lobes into the left and right hemisphere. The corpus callosum allows for both hemispheres to communicate and transfer information! The primary function of the corpus callosum is to integrate sensory, motor, and cognitive performance between the cerebral cortex.
Ins severe cases of epileptic seizures, a corpus callosotomy is performed, which cuts the corpus callosum in half. This prevents the seizures from becoming more severe, and the brain can reprogram, through neuroplasticity.
Answer:
Explanation:
PV = nRT
We are to get the answer for the volume. Hence we make V the subject of the formula.
V = nRT/P
Where n= 0.250, R= 0.0821, P= 0.92 and T = 298
V = (0.250×0.0821×298)÷0.92
V = 6.11645÷0.92
V = 6.64
V = 6.6L
