Answer: it releases enough energy to cause great damage to buildings
The characteristic of nuclear fusion makes it hazardous is option d. it releases enough energy to cause great damage to buildings.
What is nuclear fusion?It is the process where one or more light nuclei should be fused together for producing the heavier nucleus where there is a mass deficiency that should be released like the energy.
Therefore, based on this we can say that the option d is correct.
And, the rest of the options are considered to be wrong.

Explanation:
When a metal ion is formed, the corresponding ion is smaller than the atom from which it was formed.
Oftentimes, the formation of a metal ion leads to the loss of an entire shell. The reduces the ionic radius compared to the atomic radius. Hence the metal ion is always much smaller than the metal atom.

Which drawing is a structural model of C3Hg?
Answer:
The correct option is C
Explanation:
The structural model of C₃H₈ is that of option C.
In Structural model which can also be known as structural formula, the atoms of a molecule or compound are identified by the location of chemical bonds that exists between them. A structural formula is seen to consist of symbols. In this case, the atoms are connected by short lines. These short lines actually represent their chemical bonds. Where one, two, or three lines that connect each element that make up the compound stands for single, double, or triple bonds, respectively.
Answer:
C
Explanation:
Is hydrogen the right answer y’all?
Answer:
The correct answer is hydrogen.
Explanation:
Stars in the main sequence will remain in the main sequence as long as their cores contain hydrogen atoms. This is because main sequence stars run on the hydrogen atoms within their core to prevent them from falling to the force of gravity. Once these hydrogen atoms run out, the star is no longer considered a main sequence star, gravity takes hold, and the star collapses.

How many moles of calcium are in 425 grams?
Answer:
10.6
Explanation:
10,604 in other words not in a decimal
There are 10.6 moles of calcium in 425 g of calcium.
Given to us is the mass of calcium which is 425 g, we also know the molar mass of the calcium which is 40.08 g/mol
To calculate the number of moles in a given mass of a substance, you need to divide the mass by the molar mass of the substance.
Using this information, we can calculate the number of moles of calcium in 425 grams:
Number of moles = Mass (g) / Molar mass (g/mol)
Number of moles = 425 g / 40.08 g/mol
Number of moles ≈ 10.61 mol
Therefore, there are approximately 10.61 moles of calcium in 425 grams.

Question 4
Calculate the nlass of 7.1 x 1024 formula units of magnesium hydroxide, Mg(OH),.
its me again this is how you find the answer. note: i dont have the periodic table to see the exact atomic mass to find the molar mass however this is the answer:
so the actual formula is Mg(OH) with a 2 as a subscript because there are 2 Mg. so with Mg(OH)2 the Molar mass is 58.32g/mol. 58.32 g/mol x 7.1x1024 = 4.1x1026g

A student made copper sulfate using 0.250 moles of copper oxide and 0.500 moles of sulfuric acid.
Calculate the maximum mass of copper sulfate which could be produced.
Give your answer to 3 significant figures.
Relative formula mass (Mr) CuSO4 = 159.5 *
Answer:
39.9g is the maximum mass of copper sulfate which could be produced
Explanation:
1 mole of Copper oxide, CuO contains 1 mole of Cu
In the same way, 1 mole of sulfuric acid, H₂SO₄, contains 1 mole of sulfate ion, SO₄²⁻.
Thus we can understand that there are 0.250moles of Cu and 0.500 moles of SO₄²⁻ to produce CuSO₄.
The maximum moles that could be produced are 0.250 moles (Copper is limiting reactant).
To convert these moles to mass we use the relative formula mass:
0.250 moles CuSO₄ * (159.5g/mol) =
39.9g is the maximum mass of copper sulfate which could be producedIn ionic bonding, atoms _____.

A compound is made of 36.36% C, 7.13% H, 56.51% O. What is its empirical formula?
Its empirical formula : C₅H₁₂O₆
Further explanationThe empirical formula is the smallest comparison of atoms of compound forming elements.
(empirical formula) n = molecular formula
The principle of determining empirical formula and molecular formula
Determine the mass ratio of the constituent elements of the compound. Determine the mole ratio by dividing the elemental mass with the relative atomic mass obtained by the empirical formulaAr C = 12 g/mol
Ar H = 1 g/mol
Ar O = 16 g/mol
mol ratio of C : H : O =
[tex]\tt \dfrac{36.36}{12}\div \dfrac{7.13}{1}\div \dfrac{56.51}{16}\\\\3.03\div 7.13\div 3.53\rightarrow divided~by~smallest(3.03)\\\\1\div 2.4\div 1.2(\times 10)\rightarrow 5\div 12\div 6[/tex]
which of the following elements is a metalloid
Traditionally they include boron from group 3A, silicon and germanium in group 4A, aresnic and antimony in group 5A and tellurium from group 6A, although sometimes selenium, astatine, polonium and even bismuth have also been considered as metalloids. Typically metalloids are brittle and show a semi-metallic luster.
The six commonly recognised metalloids are boron, silicon, germanium, arsenic, antimony, and tellurium. Five elements are less frequently so classified: carbon, aluminium, selenium, polonium, and astatine.

Step 1: Define
7.00 moles H₂O₂
Step 2: Identify Conversions
Molar Mass of H - 1.01 g/mol
Molar Mass of O - 16.00 g/mol
Molar Mass of H₂O₂ - 2(1.01) + 2(16.00) = 34.02 g/mol

What are the spectator ions in the equation below? Select all that apply.
Pb(NO3)2(aq) + H2SO4(aq) → PbSO4(s) + 2 HNO3(aq)
Answer:
H+ and NO3- ions
Explanation:
The Pb²+ ions react with the SO4²‐ ions to form a solid precipitate, i.e. they bond together and undergo a phase change;
On the contrary, the H+ and NO3- ions are aqueous ions before the reaction and the same after the reaction, i.e. they don't change;
Hence, the H+ and NO3- ions are spectator ions
The way to do this type of question is to consider what changes and what doesn't, look at phase changes and oxidation state changes
