Answer:
A, they get their food in the same way.
Explanation:
Some fungi can be toxic or poisonous.
Example: mushrooms. Mushrooms typically are found in forests and meadows/plains.
Some fungi are glowing, brown, and in many forms/shapes.
In conclusion, fungi all get nutrient from the dirt they grew in, forests can be moist which gives fungi excellent places to form, usually around trees, because they can absorb plenty of nutrients from the dirt.

A.
copper nitrate
B.
copper nitride
C.
copper(II) nitrate
D.
copper(IV) nitrate
E.
copper(IV) nitrite
Answer:
C. Copper (II) nitrate
Explanation:
It's an inorganic compound that forms a blue crystalline solid
Ions are the charged species of the atom that carries an extra or less electron. The chemical name of the compound Cu(NO₃)₂ based on polyatomic ions is copper (II) nitrate. Thus, option C is correct.
What is an ionic compound?An ionic compound is a type of chemical compound that is characterized by the presence of the ions or the charged species that results in electrostatic forces leading to the ionic bond formation.
The copper (II) nitrate compound is an example of an ionic compound as the Cu atom is metal and nitrogen and oxygen atoms are the non-metals. The metallic part of the compound carries a +2 charge while the non-metallic part consists of a negative charge.
Therefore, option C. Cu(NO₃)₂ can be named chemically as copper (II) nitrate.

Answer:
jayfeather friend me
Explanation:
In a toasty kitchen, your dough may proof in as little as an hour (or less!). When the temperatures dip, it can take much longer—upwards of two or even three hours.
A boy sets up a picnic on the beach next to a sand dune. how are sand dunes formed?
Answer:
Sand dunes are created when wind deposits sand on top of each other until a small mound starts to form. Once that first mound forms, sand piles up on the windward side more and more until the edge of the dune collapses under its own weight.
6. An unknown compound is analyzed and found to consist of 49% carbon, 2.7
% hydrogen, and 48.2 % chlorine. If the molecular mass of the compound is 150,
what is the molecular formula of the compound?
Answer:
Molecular formula = C₆H₄Cl₂
Explanation:
Given data:
Percentage of hydrogen = 2.7%
Percentage of carbon = 49%
Percentage of chlorine = 48.2%
Molar mass of compound = 150 g/mol
Molecular formula = ?
Solution:
Number of gram atoms of H = 2.7 / 1.01 = 2.67
Number of gram atoms of Cl = 48.2 / 16 = 1.36
Number of gram atoms of C = 49 / 12 = 4.08
Atomic ratio:
C : H : Cl
4.08/ 1.36 : 2.67/1.36 : 1.36/1.36
3 : 2 : 1
C : H : Cl = 3 : 2 : 1
Empirical formula is C₃H₂Cl.
Molecular formula:
Molecular formula = n (empirical formula)
n = molar mass of compound / empirical formula mass
Empirical formula mass = 12×3 + 1.01 ×2 + 35.5 = 73.52 g/mol
n = 150 / 73.52
n = 2
Molecular formula = n (empirical formula)
Molecular formula = 2 (C₃H₂Cl)
Molecular formula = C₆H₄Cl₂

how many moles are in 4.38 of AgNO2
Answer: 0.02 moles
Explanation:
The number of moles in 4.38 g of AgNO₂ is equal to 0.028 mol.
What is a mole?A mole can be described as a standard unit that can be utilized to calculate a given number of particles. The constituents counted are usually individually distinct but identical entities.
A mole of the substance can be used to calculate quantities of atoms, molecules, ions, or other particular particles. The quantity of matter can be described as measured by elementary entities.
The number of constituents present in one mole is equal to 6.023× 10 ²³ which is known as Avogadro’s constant.
Given, the mass of AgNO₂ = 4.38 g
The mass of one mole of AgNO₂ = 153.87 g
The number of moles of in 4.38 g of AgNO₂ = 4.38/153.87 = 0.028 mol
Therefore, the number of moles of AgNO₂ is equal to 0.028 mol.

Explain why sometimes in a lab it seems like the conservation of mass isn’t accurate (but we know we haven't truly lost any mass)
Answer:
The law of conservation of mass states that in a closed system, the whole mass is conserved.
But the law of conservation of mass is not accurate sometimes in lab because in every chemical reaction, mass is converted into energy and not the whole mass can be conserved. Energy in chemical reaction can be created only by destroying the mass and not from any other means.
This is why, sometimes in a lab it seems like the conservation of mass isn’t accurate.
