Answer:
Basically no it doesnt it stays the same it just means your adding more onto the atomic number and it keeps position
As the atomic number increases along a row of the periodic table, additional electrons are added to the same, outermost shell. The radius of this shell gradually contracts as the attraction between the additional electrons and the nucleus increases.
Explanation:
Answer:
On average, agriculture accounts for 70 percent of global freshwater withdrawals. In the last 30 years, food production has increased by more than 100 percent. FAO estimates that about 60 percent more food will be needed by 2050 to meet the food requirements of a growing global population.
Explanation:
Because i learnt this before and i aced a test about it dont worry
Combinations of different metals form alloys. An alloy composed by mercury and other metal (or metals) forms amalgam. When a true alloy is formed, the component metals are mixed together at a temperature which is greater than the melting point of all of them.Apr 7, 2017
<h3>the different modes of reproduction in animals such as butterflies, mosquitoes, frogs, cats, and dogs (sexual and asexual)??? </h3>
Ans: <em><u>Dogs, cats, frogs, butterflies, mosquitoes, and many other animals reproduce by sexual reproduction. Animals have gonads, organs that produce egg or sperm.</u></em>

Ans: <em><u>your answer is in above </u></em>
<h3>b. Cut and paste pictures of animals and their young that are reproduced asexually(butterflies, mosquitoes) ????</h3>
Ans: <em><u>your Answer is in above </u></em>
This question is incomplete, the complete question;
A reaction between liquid reactants takes place at 16°C in a sealed, evacuated vessel with a measured volume of 10.0 L . Measurements show that the reaction produced 37.g of dinitrogen monoxide gas.
Calculate the pressure of dinitrogen monoxide gas in the reaction vessel after the reaction. You may ignore the volume of the liquid reactants. Round your answer to 2 significant digits.
Answer:
Explanation:
Given that;
Volume = 10.0 L
Temperature T = 16°C = ( 16 + 273) = 289 K
we know that molar mass of N₂O = 44 g/mol
number number of moles n will be: weight/molar mass = 37/44 = 0.8409 moles
Universal Gas constant R = 0.0821 atm.mol⁻¹.k⁻¹
pressure p = ?
from the ideal gas law
PV = nRT
P = nRT / n
so we substitute
P = (0.8409 mole × 0.0821 atm.mol⁻¹.k⁻¹ × 289 K) / 10.0 l
P = 19.95195 / 10.0
P = 1.9952 atm
