Answer: Na2C2O4 probably sodium oxalate

Explanation: assume you have 100 g substance.

Mass of Na is m(Na) = 34.31 g, m(C) = 17.93 g and m(O) = 47.76 g.

Calculate moles n(Na) = 34.31 g/22.99 g/mol= 1.49 mol.

For C n(C) = 1.49 mol and n(O) = 2.985. You divide all by 1.49 you

Get n(Na) : n(C) : n(O) = 1:1:2 M(NaCO2) = 67 g/mol.

Divide 134:67 = 2. You get formula Na2C2O4

What is the answer for this please ?<br> HNO3 + OH →
BartSMP [9]

Answer:

HNO3(aq) + OH-(aq) → NO3-(aq) + H2O(l)

Explanation:

According to Bronsted-Lowry theory, an acid is a substance that donates a proton (H+) and produces a conjugate base while a base is a molecule or ion which accepts the proton.

An example of Bronsted-Lowry acid and base is Nitric acid, HNO3 and hydroxide ion, OH- respectively as shown in the given reaction.

Thus, the nitric acid acts as an acid by donating a proton to the hydroxide ion which accepts it, thus producing nitrate ion, NO3- as a conjugate base, while OH- produces H2O as a conjugate acid.

Match the wave with its definition. (Lesson 4.03-4.03)
Lady_Fox [76]

The correct wave that matched its definition is:

  • Transverse Wave - A wave that has a disturbance that is perpendicular to the wave motion. The wave motion is moving side to side, the energy will be moving up and down.

  • Longitudinal Wave - The disturbance is parallel to the wave motion. In a longitudinal wave, the energy, and the motion

A wave is known to be a disturbance that travels through a medium and transfers energy from one point to another without causing any permanent displacement of the medium itself.

We have two forms of wave namely the transverse waves and the longitudinal waves.

When the vibration of a medium is perpendicular to the wave direction, the kind of wave formed is known as a transverse wave.

When the vibration of a medium is parallel to the wave direction, the kind of wave formed is known as a longitudinal wave.

An object has a velocity of 8m/s and a kinetic energy of 480 j what is the mass of the object
MariettaO [177]
Kinetic energy=Ek
Ek=(1/2)mv²
Ek=480 J
v=8 m/s
mass=?

Ek=(1/2)mv²
480 J=(1/2)m(8 m/s)²
480 J=(32 m²/s²) m
m=(480 J)/(32 m²/s²)=15 kg

answer: the mass of the object is 15 kilograms.

What 3 characteristics of matter does chemistry deal with?
taurus [48]
Chemistry is concerned with:

1) Composition
The composition of matter helps determine how it will behave chemically and physically, and is studied in chemistry

2) Structure
The structure of a certain element or compound also governs how the substance behaves, making it another vital aspect of chemistry

3) Behavior
The behavior of substances is studied in order to have explanations presented for it, expanding our understanding.
