Primera Ley de Newton. La Primera Ley de Newton declara que un objeto permanecerá en reposo o en movimiento uniforme en línea recta a menos que sea actuado por una fuerza externa. Puede verse como una afirmación sobre la inercia, que los objetos permanecerán en su estado de movimiento a menos que una fuerza actúe para cambiar el movimiento.

10.0 mL of a HF solution was titrated with a 0.120 N solution of KOH; 29.6 mL of
Ilia_Sergeevich [38]

Answer:

0.355 N of HF

Explanation:

The titration reaction of HF with KOH is:

HF + KOH → H₂O + KF

<em>Where 1 mole of HF reacts per mole of KOH</em>

<em />

Moles of KOH are:

0.0296L × (0.120 equivalents / L) = 3.552x10⁻³ equivalents of KOH = equivalents of HF.

As volume of the titrated solution was 10.0mL, normality of HF solution is:

3.552x10⁻³ equivalents of HF / 0.010L =<em> 0.355 N of HF</em>

Which of the following best describes what led to London’s “killer fog” in 1952? a. Pollution from the air contaminated the wate
abruzzese [7]
<span>b. Millions of coal fires and stagnant air caused toxic fumes to build up in the air. The main cause of the coal fires, which burned at plants across England, was a weather pattern that produced cooler weather and air that did not circulate. Citizens used more heat and so more coal was burned. The post-war coal was not great quality and thereby included many toxins. The weather pattern created fog, which after it dispersed, left toxins and acid droplets to fall on the people.</span>

Reika [66]

Answer:

coevolution

Explanation:

Coevolution plays a key role in shaping the biodiversity on Earth. Coevolution is commonly defined as reciprocal evolutionary changes brought about by interactions between species, implying that interacting species impose selection on each other(Science direct).

We can see that the change that occurred in the plants of the tropical rainforests is closely related to their link to birds. The fruits evolved an attractive color so that birds, having evolved to eat the brightly-colored fruits, may eat them.
