Introduction

Knowledge of how rapidly reaction proceeds is among the most important for practice in chemistry and chemical engineering. We often use casual descriptions of reaction rate such as “slow” or “fast” in our lives, however, such information can be scarcely enough for practical and industrial applications, such as running a chemical plant, for example. While there is a huge spectrum of the reaction rates that are present in nature – from the extremely slow steel oxidation to extremely rapid gas combustion, the quantitative measure is needed to compare them practically. For a general reaction in solution:

Responding to emergency situation requires constant preparation in anticipation of an untoward event. Auf der Heide’s disagreement to the assumption that disaster response is an extension of daily emergency procedures is apparently true to my perspective. This is because disaster constitutes a test for emergency response and to be able to make an adequate response, planning is essential to the process (Auf Der Heide, 2005). On a more personal ...

Group 1 elements are referred to as alkali metals because they form oxides and hydroxides that dissolve in water producing alkaline solutions. They have one electron in their outer shell that they lose by oxidation to form ions; Na Na+ + e- that is more stable (Schwerdtfeger et al. 7520). As one move down the group 1, the elements atom gets larger as the outer shell electron get easily lost and its radius is governed by the number of layers of electrons around a nucleus and the pull of outer electrons feel from the nucleus, therefore group one element get more ...

DHEA:

Dehydroepiandrosterone, or DHEA, is a hormone the human body produces via the adrenal glands, which are above the kidneys. The exact effect of DHEA is not yet fully identified; however, it is believed to be a precursor of the female and male sex hormones, namely estrogen and testosterone, among others. Precursors are substances that the body converts into hormones.

The production of DHEA usually reaches its peak around the mid-20s and declines ever after. The same applies to estrogen and testosterone, whose production also declines with age. For that reason, if an individual wants to increase their hormone levels, it ...

ABSTRACT

The research argues that although a gas flaring stoppage is not successfully in-place in Nigeria, fitting the appropriate technology with complementary economic and institutional factors can lead to near-zero or zero gas flaring. Nigeria is a developing country with a unique culture of many tribes and one of the largest growing urban populations in the world. Infrastructural, political and economical challenges to meeting the goal are introduced. Reinjection of gas back into wells is not available as an option to gas flaring because a large region for gas production is wetlands (Buzcu-Guven et al. 2012). Wetlands ...
