Answer:

50 m/s^2

Explanation:

In this case, we're using Newton's Second Law: Force = mass × acceleration.

We are given the force as 250 newtons and the mass as 50 kg, so 250/50 = 50 m/s^2.

Have a lovely rest of your day/night, and good luck with your assignments! ♡

Answer: The acceleration is 50.

Explanation: You can actually re-arrange the formula F = ma to F/m = a. 250/50 = 50.

Which combination of reagents used in the indicated order with benzene will give m-nitropropylbenzene? a. 1) CH3CH2CH2Cl/AlCl3,
VladimirAG [237]

Answer:

1) HNO3/H2SO4, 2) CH3CH2CH2Cl/AlCl3

Explanation:

Benzene is a stable aromatic compound hence it undergoes substitution rather than addition reaction.

When benzene undergoes substitution reaction, the substituent introduced into the ring determines the position of the incoming electrophile.

If I want to synthesize m-nitropropylbenzene, I will first carry out the nitration of benzene using HNO3/H2SO4 since the -nitro group is a meta director. This is now followed by Friedel Craft's alkykation using CH3CH2CH2Cl/AlCl3.

If the density of pure water is 0.9922 g/mL at 40 ºC, calculate its theoretical molarity at that temperature. Report to 4 sig fi
OleMash [197]
Answer is: theoretical molarity of water is 55.1222 mol/L.<span>
d(H</span>₂O) = 0.9922 g/mL.
M(H₂O) = 2 · Ar(H) + Ar(O) · g/mol.
M(H₂O) = 2 + 16 · g/mol = 18 g/mol.
c(H₂O) = d(H₂O) ÷ M(H₂O).
c(H₂O) = 0.9922 g/mL ÷ 18 g/mol.
c(H₂O) = 0.0551 mol/mL.
c(H₂O) = 0.0551 mol/mL · 1000 mL/L = 55.1222 mol/L.

Identify the products formed in this Brønsted-Lowry reaction.<br><br> HPO2−4+NO−2↽−−⇀acid+base
klemol [59]

Answer: The products formed in this Bronsted-Lowry reaction are HNO_{2} and PO^{2-}_{4}.

Explanation:

According to Bronsted-Lowry, acids are the species which donate hydrogen ions to another specie in a chemical reaction.

Bases are the species which accept a hydrogen ion upon chemical reaction.

For example, HPO^{2-}_{4} + NO^{-}_{2} \rightleftharpoons HNO_{2} + PO^{2-}_{4}

Here, the products formed in this Bronsted-Lowry reaction are HNO_{2} and PO^{2-}_{4}.

Thus, we can conclude that the products formed in this Bronsted-Lowry reaction are HNO_{2} and PO^{2-}_{4}.

Which of the statements about elements is true?
Jet001 [13]

1. No two elements have the same kind of atom.

Explanation:

The correct of all statement is that no two elements have the same kind of atoms.

Every element have different atoms.

  • Over a hundred elements have been identified by scientists.
  • Atoms are the smallest particles that takes part in chemical reactions.
  • Elements are distinct substances that cannot be split.
  • Atoms of all elements do not have the same mass and volume. Isotopes are examples.
  • It is true that atoms of all elements have different masses and also different volumes.
  • The volume of an atom is function of the number of electrons it contains.
