I agree with idea of Kevin because bakong soda dissociates faster in hot water than cold water.

Baking soda is a chemical that can undergo a decomposition reaction when heated. At 80 degrees Celsius, sodium bicarbonate starts to break down into sodium carbonate (Na2CO3), water (H2O) and carbon dioxide (CO2) which is ready for reaction with other chemical.

So we can conclude that Kevin idea is correct because bakong soda dissociates faster in hot water than cold water.

Given the Planck's constant and the speed of light, the energy of the ultraviolet light with a frequency of 9.58×10¹⁴ Hz is 6.35×10¯¹⁹ J (Option C)

The energy of the ultraviolet light can be obtained as follow:

E = hf

E = 6.626×10¯³⁴ × 9.58×10¹⁴

E = 6.35×10¯¹⁹ J

Copper will turn green and calcium will turn orange.  this is as a result of the atomic transitions visible in line spectra

Transition elements are substances with partially filled d orbitals, sometimes referred to as transition metals. According to IUPAC, a transition element is an element with a partially filled d subshell or one with the capacity to create stable cations that has an unfilled d orbital.

As a result of their transitional behavior between s-block or p-block elements, the d-block elements are referred to as transition elements. Their characteristics are intermediate between those of the covalently-bonded, highly reactive s-block metallic elements and those of the p-block elements.

Answer:

The Bohr model show the protons in a carbon atom using the model;  "Electrons move in fixed orbits around a nucleus of protons and neutrons."

According to Bohr's model of the atoms, the Rutherford model is basically correct. This implies that Bohr model accepts the idea of a nucleus containing nucleons(protons and neutrons).

In addition, the model also postulates that electrons are found in fixed orbits. These fixed orbits are called energy levels or shells.

Explanation:

ik it is write

Answer:

d=3.95 g/l

Explanation:

1) Ideal gas equation:

pV = nRT

2) Transform the equation to compute density, d = m / V

n = mass in grams / molar mass = m / MM

pV = (m/MM) RT

=> pV = mRT/MM

=> m/V = pMM / (RT)

d = pMM / (RT)

p = 1.21 atm

MM = 83.80 g/mol (this is the atomic mass of krypton element)

T = 50 + 273.15 K = 323.15K

3) Compute:

d = (1.25 atm * 83.80 g/mol) / (0.0821 atm*liter /K*mol * 323.15K)

The limiting reactant here is P4O10 . The percent yield of the product is caculated as 33.3%.

The limiting  reactant is the reactant that is in a minute quantity.

Number of moles of P4O10 =  85.5 g/284 g/mol = 0.3 moles

Number of moles of H2O =  74.9 g / 18 g/mol = 4.2 moles

From the reaction equation;

1 mole of P4O10 reacts with 6 moles of H2O

x moles of P4O10 reacts with 4.2 moles of H2O

x = 0.7  moles

Hence, P4O10 is the limiting reactant.

1 mole of P4O10 yields 4 moles of H3PO4

0.3 moles of P4O10 yields

0.3 moles * 4/1 = 1.2 moles

Mass of the H3PO4 = 1.2 moles * 98 g/mol = 117.6 g

Percent yield = 39.2 g/117.6 g * 100/1 = 33.3 %

In the galvanic or voltaic cell, the standard cell potential is 1.67 V. The standard potential is the difference between the reduction potential of cathode and anode.

An electrochemical cell produces energy by a sponteanous chemical process. A galvanic or voltaic cell produces energy by a sponteanous chemical reaction.

Hence, given the standard reduction potentials;

Sn4+ + 2e- ==> Sn2+  Eº = 0.15 V (anode)

Co3+ + 2e- ==> Co2+  Eº = 1.82 V (cathode)

Eºcell = 1.82 V - 0.15 V = 1.67 V

Answer:

c, 8.32 mol

Explanation:

the molecular mass of water is about 18.02, to get the moles of water 150/18.02=8.32 mol, since the coefficients of HCl and H2O are the same, the number of moles would be the same as well

The ion had 4+ charge when it had 86 electrons, so it should have no charge on it if there are 4 more electrons and the atom will be neutral.

And since we know that number of electrons in a neutral atom is equal to Atomic Number of that atom.

So, at neutral phase, it had 86 + 4 = 90 electrons

hence, our required atom is : Thorium

And it's ion will be ~[tex]\sf Th^{4+} [/tex]
