The objects potential energy at point Y is less its potential energy at which of the following points

Answer:

Explanation:

The balanced chemical equation is Cl2 + 2KBr → 2KCl + Br2. The amount of bromine is calculated as follows:

11.0 g KBr (1mol KBr/119.002g KBr * 1mol Br2/2mol KBr * 159.808g Br2/1mol Br2= 7.39 g Br2.)

Answer:

The correct answer is - tin.

Explanation:

Tin is the element that is mixed with copper to make bronze as bronze has many unique properties such as crisp sound quality and hardness. The hardness of the bronze allows them to make a good quality sound is come by adding tin to copper restricts the free flow of electrons of the copper atoms.

The pure metals have molecules present in an orderly manner and allow the electrons to free flow. This is why bell makers use bronze as it does not allow electrons to move freely which makes it hard and makes a good sound.

Answer:

1: The speculation that continents might have 'drifted' was first put forward by Abraham Ortelius in 1596. The concept was independently and more fully developed by Alfred Wegener in 1912, but his hypothesis was rejected by many for lack of any motive mechanism. 2: The most obvious evidence for continental drift is that the continents appear to fit together like pieces of a puzzle. But scientists were skeptical , and Wegener needed additional evidence to support his hypothesis. Glaciers covered large areas that are now parts of these continents.

Answer:

1. D

2. C

Explanation:

1. Although now accepted, the theory of continental drift was rejected for many years, with evidence in its favor considered insufficient. One problem was that a plausible driving force was missing. A second problem was that Wegener's estimate of the speed of continental motion, 250 cm/year, was implausibly high.

2.The most obvious evidence for continental drift is that the continents appear to fit together like pieces of a puzzle. But scientists were skeptical , and Wegener needed additional evidence to support his hypothesis. Glaciers covered large areas that are now parts of these continents.

Answer:

5 hours.

Explanation:

Given that,

Initial time, [tex]T_i=6\ pm[/tex]

Final time, [tex]T_f=11\ pm[/tex]

We need to find how much time did it take the car to arrive.

Time =  final time-initial time

= 11 pm - 6 pm

= 5

So, it takes 5 hours by car to arrive.

Answer:

15 moles  of CO₂

Explanation:

Given data:

Number of formula units = 8.9 ×10²⁴ formula units

Number of moles of CO₂ = ?

Solution:

The given problem will solve by using Avogadro number.

The number 6.022 × 10²³ is called Avogadro number.

1 mole = 6.022 × 10²³ formula units

8.9 ×10²⁴ formula units  × 1mol / 6.022 × 10²³ formula units

1.5 mol ×10¹ mol

15 moles

Explanation:

This law states that a still object will stay still unless a force pushes or pulls it. A moving object will stay moving unless a force pushes or pulls it. Gravity and friction are forces that constantly push and pull the "stuff" on earth. So, when we roll a ball, it slowly comes to a stop.

When there is an exothermic reaction so here the average kinetic energy of the particles of matter ib the products is option 1. decrease.

In terms of thermochemistry, an exothermic reaction means the reaction where the total standard enthalpy should change so ΔH⚬ is negative. Also it should be release heat.

So based on this, When there is an exothermic reaction so here the average kinetic energy of the particles of matter ib the products is option 1. decrease.

Answer:

They may have different phenotypes because of differences in their environments, such as nutrition and healthcare. Why might genetically identical twins have different phenotypes?  Any genes on the same chromosome could be linked genes, whereas only genes on sex chromosomes can be sex-linked genes.

Explanation:

Due to the effects of the environment, genetically identical twins might have different phenotype.

The qualities or visible characteristics of an organism are its phenotype. It depends on how the environment and the genotype, or genetic code, of the organism interact.

Although human monozygotic twins as well as other genetically identical species may share startling physical similarities, they frequently differ in key characteristics, such as complicated diseases. The effects of the environment have generally been blamed for this variance across organisms with essentially identical chromosomal DNA sequences.

Therefore, due to the effects of the environment, genetically identical twins might have different phenotype.

Answer:

True

Explanation:

Limiting reagent is the reactant that determines the progress of the reaction. It determines how much of the product is formed.

The equation for this reaction is;

NaCl (aq) + NH4HCO3 (aq) → NaHCO3 (aq) + NH4Cl (aq)

From the reaction, 1 mol of NaCl reacts with 1 mol of NH4HCO3 to produce 1 mol of NaHCO3

Converting to masses using; Mass = Number of moles * Molar mass

58.44g of NaCl reacts with 79.056g of NH4HCO3

If we were to  sue the whole 1.2 g of NH4HCO3 we would require xg of NaCl

58.44 = 79.056

x = 1.2

x = 0.887g

The fact that 1.2g of NH4HCO3 requires 0.887g of NaCl (which is less than the available 0.75g) means that NaCl is the limiting reagent.
