Because the atoms are separating bc of the heat. A solid has really compact atoms so if it was melted its atoms would become looser and form a liquid
Answer is (3) - metalloid
Elements in group 14 can be classified as non metals, metalloid and metals. Group 14 has C, Si, Ge, Sn and Pb as its elements. C is a non metal. Si and Ge are metalloids while Sn and Pb are metals.
Metalloids are elements which share both non-metallic and metallic characteristics.
The element in group 14, period 3 on the periodic table is Si. Si is a semiconductor means Si can conduct electricity but not good as metals. Conducting electricity ia one of metallic property.
Answer:
1.0M HCl is the concentration of the acid
Explanation:
Based on the reaction, 1 mole of NaOH reacts per mole of HCl. That means the moles added of NaOH in the neutralization = Moles of HCl in the solution. With the moles and the volume in Liters we can find the molar concentration of HCl
<em>Moles NaOH = Moles HCl:</em>
25.0mL = 0.025L * (2.0moles / L) = 0.050moles HCl
<em>Molarity:</em>
0.050moles HCl / 0.0500L =
<h3>1.0M HCl is the concentration of the acid</h3>
The percentage yield of the new production technique is 82.8%
<h3>What is the percentage yield?</h3>
Production is the procedure by which finished products are obtained form the raw materials. The production process involves the passing of raw materials through a certain procedure that involves the use of certain machines and equipment to give us the required products.
We are told in the question that there are three shifts;
Shift 1 produces 4562 grams
Shift 2 produces 5783 grams
Shift 3 produces 5247 grams
Average production from the three shifts = 4562 grams + 5783 grams + 5247 grams/3 = 5197 grams
The theoretical average yield is = 7000 grams + 7000 grams + 7000 grams/3 = 7000 grams
Now the percentage yield = actual yield/ theoretical yield * 100/1
percentage yield = 5197 grams/7000 grams * 100/1
percentage yield = 82.8%

Through the erosion and indentations. Formation down cutting it leaves forms of a river or ocean carved. Using range you can see how the floor of the canyon were an ocean floor. Erosion is caused by water the Grand Canyon sits on a body of water unlike most canyons this one happened to erode and sediment the body where the water once was. A layer of rock is also apparent which you wouldn’t be able to see unless erosion happened and etc.
