Answer:

LHS-RHS

1 C - 1 C

4 H-2 H

2 O- 3 O

So on right side 2 hydrogen are less and one oxygen is more..so

Balanced equation is

CH4+2O2==CO2 + 2H2O

Hey there!

CH₄ + O₂ → CO₂ + H₂O

Balance H.

4 on the left, 2 on the right. Add a coefficient of 2 in front of H₂O.

CH₄ + O₂ → CO₂ + 2H₂O

Balance C.

1 on the left, 1 on the right. Already balanced.

Balance O.

2 on the left, 4 on the right. Add a coefficient of 2 in front of O₂.

CH₄ + 2O₂ → CO₂ + 2H₂O

Our final balanced equation: CH₄ + 2O₂ → CO₂ + 2H₂O

Hope this helps!

what is the change in the velocity of the biker below as he travels from point b to point c ? ..... What is his acceleration fro

Furkat [3]

The change in the velocity = 4 m/s

Acceleration = 4 m/s²

<h3>Further explanation</h3>

Given

vo = initial velocity = 4 m/s

vf = final velocity = 8 m/s

t = 1 s

Required

The change in the velocity

Acceleration

Solution

the change in velocity =

$\tt vf-vo=8-4=4~m/s$

Acceleration = ratio of a change in velocity and the time

$\tt a=\dfrac{\Delta v}{t}= \dfrac{vf-vo}{t}$

Input the value :

$\tt a=\dfrac{4~m/s}{1~s}=4~m/s^2$

Which of the following mixtures may be act as a buffer solution?

lions [1.4K]

Answer:

B) HF, NaF

Explanation:

A buffer solution is made up of a weak acid and its conjugate base.
In this case, HF is a weak acid and NaF is the conjugate base, therefore the mixture of HF, and NaF would make a perfect buffer solution.
The buffer would have the weak acid HF and its conjugate base, F- which comes from the soluble salt NaF.

A 4.24 kg marble slab has the volume of 1564 cm3 What is the density in g/cm3

miskamm [114]

Answer:

The answer is

Explanation:

The density of a substance can be found by using the formula

$density = \frac{mass}{volume} \\$

From the question

volume of marble = 1564 cm³

1 kg = 1000 g

4.24 kg = 4240 g

mass = 4240 g

The density is

$density = \frac{4240}{1564} \\ = 2.710997442...$

We have the final answer as

La etiqueta de una bebida transparente con un ligero toque anaranjado indica que contiene aga con un 15 porciento de zumo de nar

Brilliant_brown [7]

<u>Respuesta:</u>

16 gramos de vitamina C y 8 gramos de colorantes.

Explanation:

Debemos multiplicar el porcentaje de cada componente por la cantidad total (100 %) de zumo.

800 g de zumo = 100%

- Tenemos un 2 porciento (2 en 100 o 2/100) de vitamina C. Por lo tanto, la cantidad en gramos de vitamina C es:

2/100 x 800 g = 16 g

- Tenemos un 1 porciento de colorantes en el zumo (1/100). Por lo tanto, la cantidad en gramos de colorantes es:

1/100 x 800 g = 8 g
