An example of a scientific law is the law of conservation of mass, which states that matter is neither created nor destroyed in

a chemical reaction.Based on what you know about scientific laws in general, classify the following statements regarding the law of conservation of mass as true or false.A) It was developed from past observationsB) It is subject to experimentation and revision.C) It explains why mass is conserved.D) It predicts future observations.

Explanation:

According to the law of conservation of mass, it makes a generalized observation that there will occur no change in the mass of a substance even if it undergoes a chemical reaction.

Whereas this law of conservation does not explain any phenomenon of why this conservation of mass occurs.

Therefore, the given statements are classified as follows.

A) It was developed from past observations - Ture

B) It is subject to experimentation and revision - True

C) It explains why mass is conserved - False

D) It predicts future observations - True

Based on the activity series provided, which reactants will form products? F &gt; Cl &gt; Br &gt; I CuI2 Br2 Right arrow. Cl2 Al
AleksAgata [21]

The reactants based on the reactivity capable of forming the products are \rm CuI_2\;and\;Br_2. Thus, option A is correct.

The reactivity series has been the arrangement of the elements based on their reactivity. The highly reactive element has been capable of replacing the less reactive element in the compound, and form the product.

In the following reactions, the new product has been formed by:

  • \rm CuI_2\;and\;Br_2

From the reactivity series, Br has been more reactive than I, and thereby replaces iodine in the compound for the formation of product.

  • \rm Cl_2\;and\;AlF_3

The compound has been formed with F. Cl has been less reactive than F, and will not be able to form the product.

  • \rm Br_2\;and\;NaCl

The compound has been formed with Cl. Br has been less reactive than Cl, thus will not displaces Cl for the formation of new product.

  • \rm CuF_2\;and\;I_2

The compound has been formed with F. I has been less reactive than F, and will not be able to form the product.

The reactants that will be able to form the products have been \rm CuI_2\;and\;Br_2. Thus, option A is correct.

What answer names a producer in an ecosystem
Temka [501]

Answer:

Fir tree

Explanation:

Producers, Consumers, and Decomposers in the Forest Community. Producers are any kind of green plant. Green plants make their food by taking sunlight and using the energy to make sugar. The plant uses this sugar, also called glucose to make many things, such as wood, leaves, roots, and bark. Rabbit, Fungus, and raccoon are all decomposers!

Corn plants may be tall (TT or Tt) or short (tt). The breeding of two parent corn plants results in offspring that are all tall.
zubka84 [21]

Answer:

0%

Explanation:

  • The probability that both of the parents are homozygous recessive is zero.
  • In our case, The gene for tallness is dominant over the gene for dwarfism
  • Therefore; TT is homozygous dominant while tt is homozygous recessive and Tt is heterozygous.
  • Heterozygous genotype (Tt) will exhibit a tall phenotype.
  • When two parents are crossed and all the offsprings are tall then the possible genotype of the parents is either;
  1. Homozygous dominant for both parents or  

       TT x TT

    2. One parent is homozygous dominant and the other is homozygous recessive.

        TT x Tt

  • Therefore, the probability of having both parents as homozygous recessive when all the offspring are tall is Zero.
